It can, but it is not a fire proof way of doing it. Typically, the larger the comb, the older the hen.
But, this can also mean that it is the domninant hen of the flock (and is not necessarily older than the others).
Then there are some breeds which have comb types which cannot be used to identify age (such as Ameraucanas or Leghorns).
You know when a hen is ready to start laying eggs when her comb drops, and her face feathers are full and have lost the "pinkish" color.
At about 4 weeks you can start to see physical characteristics change between hens and cockerels. The young male will develop comb and wattles quicker and more pronounced. The males will be more aggressive than the hens and play fight. When they perceive danger they will come to the front and get closer to the "danger" than the hens in the same age group. They appear more curious and are quicker to investigate bugs and new objects introduced to the area they live in. Day one if you are VERY EXPERIENCED. Most hatcheries have people on staff (usually Japanese based on the need for sexing in a country with limited space) that sex day old chicks. They squeeze the chick to release fecal material then flip it over, open the vent and look for a small lump to determine male or female.
You want your hens are to the age of laying eggs (which is about 6 months), and your hens are under the age of three years (because when they reach this age, they are past their prime, and lay less eggs). Expect from your hens that every day 80% of the number of hens will be your number of eggs. So with this math, if you have 60 hens that are all in their prime, you can expect to get about 1344 eggs in four weeks.
sure. you can do this by height, surface area covered, or length u can determine the age of reefs by calculating the amount of calcium deposited.
they age of the hen that makes them lay
5 weeks :)
Take it to a Veterinarian. And they can determine the age.
The thickness of the shell (lip) increases with the age. This is how you can determine the age of the conch.
Madam Walker did not make the straightening comb. It existed in the 1870s when she still was a child. She was born in 1867.
There is no specific time for a hen to lay her eggs. Never less than 24 hours after the last egg but many hens will skip a day between eggs. Age, general health and breed determine the quantity when it comes to egg production. As long as light conditions are optimum and they get at least 14 hours of light they will produce eggs regularly until they age out and become too old to lay.
Young hens prior to laying age are called pullets.
