Incubation time will differ depending on the particular type of poultry.
For chickens the incubation time (time it takes for a chick grow to hatch) is 21 days. For turkeys, ducks and most of the other birds, incubation is 28 days.
This number is not set in stone as you can expect the eggs to "pip" (see the first cracks in the shell) at 21 or 28 days, and it may be earlier or later depending on environmental conditions.
Hatching time -- from pipping until you see a wet bit of fluff -- depends on the strength of the chick, the hen's contribution and the environmental conditions. It can be as quick as 2 hours and as long as a full day.
It is somewhere in the region of 41 days before they are ready for slaughter.
They are born with feathers. It just takes them a while to dry them off.
A fully grown chicken is one at the age of 21 weeks which is called a pullet.
3 to 4 months average
Longer than a dude, usually.
21-26 days
They need a mother until they grow feathers which might be in about a week, then you can let the mother be a normal hen again, but separate chicks from all birds
how long for my macaw to grow back feathers on his head the mother plucked them in the nest box @2 weeks old?
2-4 weeks
It might take about three months????
Long feathers take up a lot of room, and could not develop in the egg. The baby bird's down is a very efficient insulator, which helps conserve energy that it needs to survive and also for its rapid growth. Once it is of a good size and begins to need the longer feathers, they grow in.
Up to about 4 or 5 months old the rate will be roughly equal, after that Males usually feather more slowly and patchier than hens. The roosters tail will take longer as it has more to grow.
An impossible question to answer. What species? Different species spend from several days to several months as nestlings and feather growth is similarly variable in timing. What is meant by "grow"? Feathers visible in the skin or fully expanded, orthadox, feathers?
After the first year, they are not considered chicks.
Yes. The long tail feather often drop off during the first molt when all the roosters feathers are replaced by new one's. The new long feathers will take more time to regrow so be patient, they will come back. Many roosters lose the long feathers due to picking from the hens while they roost at night
Yes if they don't grow back ( although I'm not an expert)you should probably see a vet.
Between 48 to 52 weeks
Some do depending on the way you plant it. Chicks and hens are an example. You have to take the buds in the spring and put them so they are in a row. Warning chicks and hens are spread a lot.
