They or you don't need to help. The hen will do everything needed. That is her duty and she does it all instinctively. They will remain with her until she decides to introduce them to the flock. If your flock is aggressive then it may be a good idea to remove them from her and keep them in a brooder box for safety.
Yes, the hen is careful not to squash the chicks. Hens sit on the clutch of eggs for three weeks without crushing them. Once the chicks start to hatch the hen is extra careful and often gets adjusts her position. The hatching chicks will stay under the mother hen for a few days and even when they venture out, they will dive back under her for protection.
yes it can if your are wearing the right protection
Hens ovulate daily: their eggs. If their eggs are fertile there is a chance of them hatching into chicks, if incubated correctly.
Definitely NO because hens egg is chicks before hatching and when hatched when it grow up it is already rooster if the chick is a boy but if it is a girl it is a hen..
you hatch eggs to grow the chicks into chickens for their meat and eggs to eat
Ptarmigan take care of their chicks by providing protection and warmth, often leading them to food sources shortly after hatching. The mother hen is particularly attentive, using her camouflaged plumage to help conceal her chicks from predators. She also calls to them and leads them to safe areas for foraging. During the first few weeks, the chicks rely heavily on her guidance for survival.
does it really matter ??
A hen will likely not adopt chicks unless she has chicks of the same age already. Hens will protect her nest from even the smallest chicks introduced so it is not a good idea to try to force a hen to "mother" newly hatched chicks. Keep the young chicks in the brooder box until they are older and can defend themselves. It is not the rooster they need to worry about, he will ignore them, the most damage will come from older hens establishing the pecking order of the flock. Chicks and mother can be introduced back into the flock by about 2 to 3 months. There will still be some squabbling, but the chicks are old enough and fast enough to escape the worst of the punishment. Momma hen will help them. There is not much worry from the rooster.
Just let her be. The newly hatched chicks will take up some of momma's time and the room under her but the mother hen will adjust things by herself. Trying to do this for her will just stress her out and may cause her to leave the nest. The new chicks will find room under her wings eventually and mother hen will roll the unhatched eggs closer together.
By verbal communication, and even by sight. To a human all chicks peep the same, but to a mother hen, she can tell which chicks are hers and which are not.
Chickens do not feed their young. Chicks are hatched knowing how to eat and drink. Newly hatched chicks do not need food or water for up to 72 hours after they emerge from the shell, they will dry out, fluff up and start to explore their surrounding under the watchful eye of the mother hen. After a day or two they will venture out of the nest and search for food without the mothers help.
If you have obtained fertilized eggs, they can be sucessfully incubated, but the chicks MUST be kept warm after hatching. Recommended temperature after hatching is 95-99 degrees F the first week and decrease by 5 degrees each week.
