Body Weight and Frame Before First Egg

A pullet that is too light, too fat or built wrong for her breed will lay late and poorly. Here is how to check her before the first egg.

Most growers weigh a pullet once, when they collect her, and then forget about her until the first egg is late. By then the weeks that decided her frame are already behind her. A bird that is too light, too fat or built the wrong way for her breed will lay late and lay poorly, and there is very little that can be done about her build at point of lay.

This guide covers the checks you can do yourself with a scale, a pair of hands and a notebook, in the weeks before the first egg. It does not replace a breed guide or a vet. It is meant to make you look at the right things, at the right time.

Frame is not the same as weight

Weight and frame get mixed up all the time. Frame is the size and build of the skeleton: how long the breastbone is, how wide the pelvis opens, how deep the body sits. Weight is what the bird carries on that frame, which is muscle, fat and the contents of the gut. A small-framed bird can be heavy and still be fat. A large-framed bird can look thin in a crowded house and still be perfectly sound.

The breed sets the frame. A brown layer, a white layer and a dual-purpose bird are not built to the same plan, and their weights at point of lay are not the same either. That is why a weight chart from one breed is no use for another. Get the chart from your supplier or the breed's own guide, and use that. A chart copied from a neighbour's flock only tells you about the neighbour's flock.

In practice, a pullet heading for lay needs to be heavy enough to carry the eggs she is about to make, and light enough that fat is not crowding her passage. The gap between those two is narrow, and it is where most of the trouble lives.

Weighing a sample every week

Weigh the pullets the same way every time. Use the same scale, weigh at the same time of day, and do not compare a bird weighed after the morning feed with one weighed before it. Pick your sample from across the house rather than only the biggest and smallest birds. Catch them at random as they come out of the pen, not by pulling out the ones that look wrong to you.

Write the weights in the same notebook each week, with the date. A single number tells you little. The direction tells you a lot. A flock that slips below its chart for two weeks running needs its feed and space looked at. A flock that climbs faster than its chart needs the feed plan checked before the birds get fat.

The hands-on checks

A scale tells you how heavy a bird is. Your hands tell you what she is carrying. Pick the bird up gently, support her body, and check these points in order:

  1. The breastbone (keel). Run a finger along the centre of the chest to the tip of the keel. A keel that is sharp and carries little meat says the bird is thin. A keel buried under soft fat says she is over-conditioned.
  2. The pelvic bones. Feel either side of the vent. Pullets close to lay have pelvic bones that give a little and sit apart, leaving room for an egg. A hard, close pelvis means she is not ready. A padded one, with fat all round, means she may be carrying too much.
  3. The comb and wattles. As a pullet comes into lay, the comb and wattles grow, redden and get smoother and waxier. A small, pale comb in a flock that should be close to laying is a sign to look harder at feed and light.
  4. The belly. A soft, full belly after feeding is normal. A belly that stays heavy after the crop has emptied is a reason to look for fat, a gut problem, or a bird that is not laying as she should.

Why pullets end up too light or too heavy

Being off the chart is usually a feeding or housing problem rather than bad luck. The same causes come up again and again:

  • Too light. The grower feed was cut too early, a pen is overcrowded so the weaker birds lose out, or worms or disease are slowing growth. Drinkers that run dry in the afternoon heat hold weight back too.
  • Too heavy. The birds stay on a rich feed for longer than they need, they are not moving much, or they are getting scraps and treats on top of the ration.
  • Uneven. The flock was never sorted by size. Stronger birds crowd the feeder and the slower ones get less. A flock that is not even cannot be fixed with one feed change.

Harmattan adds its own pattern. On cold, dusty mornings birds can eat more to keep warm, and if the ration is rich that extra energy can settle as fat. Check the pullets in the cold months as carefully as you check them in the rains, and do not assume a bird that looks well covered is doing well.

The feed switch and what it costs

Grower and layer feeds do different jobs. The grower ration builds the frame. The layer ration is for laying, with the calcium the eggs need. Switching too early fattens a bird before she has the frame to lay. Switching too late leaves her without the feed she needs when laying starts. Confirm the switch point with your feed supplier or the breed guide. Do not switch just because the birds look big, and do not stretch the grower bag past its time because it seems cheaper week to week.

Money matters here. Feed is more than half of what a flock costs, so a pullet fed past her need is an expensive mistake. A 50 kg bag of feed is broadly GH₵400 to GH₵470, depending on brand and season, so confirm today's price before you buy in bulk. Overfeeding a whole house for a month adds up quickly, even though no single bird looks wrong.

Checking a point-of-lay pullet before you pay

Some growers buy point-of-lay pullets rather than rear them. The price is higher, and the risk is that the frame is wrong and you only find out when the eggs are late. Point-of-lay pullets are quoted in the range of GH₵1,000 to GH₵1,150, so it is worth checking before you commit.

Ask for the weight record the pullets were kept on, and ask what they were fed, when the feed was switched and what vaccines they had. When she arrives, check the keel and the pelvic bones yourself, using the points above. A bird that was built right and fed right should show both. If something does not match what you were told, raise it before the pullets go in the house with the rest of your flock.

Confirm today's price and exactly what it includes before you pay anything. The farm will go through it with you first.

Space, sorting and the first weeks in the house

The frame is set in the grower house, but it is protected or spoiled there too. Give the pullets enough floor space that every bird can reach the feeder and the drinker without a shove. Where the house is too full, the weaker birds spend the day standing back and eating less, and they show it on the scale a week or two later.

Sort the flock when it is small enough to do easily. Move the clearly smaller birds to a separate pen, feed them from their own tray, and watch them for the next few weeks. Many growers skip this because it feels like extra work. It is the cheapest fix there is, and it is what keeps a flock even on the chart.

Keep the house quiet and the routine steady. Changes in feed time, lights and handlers all show up in the weights. Write the change down in your notebook when you make it, so when a bird is off the chart you can tell which change came first.

When one bird is off the chart, do not treat her straight away. Pick her up, run the keel and pelvis checks again, and look at her droppings and her crop. Then look at the pen she lives in. If she is the only bird off the chart, the cause is usually her own: a pecking order that keeps her from the feeder, a bad foot, or a gut problem that needs a vet. If half the pen is off the chart, the cause is almost always the house, the feed or the water, and that is what you fix first.

Key takeaways

  • Frame comes from the breed and the skeleton. Weight sits on top of it, so track both.
  • Weigh a random sample the same way each week, and write the numbers down with the date.
  • Use the keel and the pelvic bones as hands-on checks, not just the scale.
  • Confirm the grower-to-layer switch with your supplier, and never switch just because the birds look big.

Questions growers ask about pullet weight

How often should I weigh pullets?

Weekly is a good habit through the growing stage. Weigh on the same day, at the same time of day, on the same scale, and record the numbers beside the date.

Can a light pullet catch up?

Sometimes, if the cause is fixed early. Feed, space and worms are the usual culprits. A bird that has been light for several weeks often starts laying late, so bring the vet in if she is not growing.

Is a fat pullet a bad pullet?

Not necessarily, but an over-conditioned pullet is more likely to lay poorly and to strain. Cut back on the rich feed, watch her for a week, and check her against the breed chart again.

Do I need a special scale?

No. A reliable hanging or kitchen scale that reads small weights clearly is enough. Use the same one every week, and check it against a known weight now and then.

Plan the frame now, then send the order form or call 024 915 1503

The weeks before lay are when a pullet's frame is finally set, so the time to plan them is before the first egg, not after it. If you are starting a layer flock, send the order form on our site or call 024 915 1503. An order starts with a message, not with money. We confirm the price, the hatch date and the delivery cost with you before any payment, and the minimum order is one box of 50 chicks.
