If a hen ever does that it means she is rejecting her babies because she cant provide the proper needs for it, So if she can she will sit on her babies for most of the time she will only leave when felt threaten. A chicken can not protect her babies while their in a shell, It will be hard for her to take them with her so the only time you will see a nest filled with eggs but no mum is when she dumps them or if a farmer has distracted the mom so he can collect the eggs!
Hope this helped.....
To keep them warm so they can hatch.
The hen will lay eggs either way, she will lay more if you have a rooster and the eggs will be fetilized
Broody hens do lay eggs. They actually lay one [1] egg every day or two.
Hens lay eggs, the ones you eat.
Hens are chickens.Hens are female chickens and lay eggs.Roosters are male chickens and do not lay eggs.So your answer is YES, you need a hen to lay eggs.
They sit on them as soon as the egg is laid. They will continue sitting on the eggs until they hatch. This keeps the eggs warm. If you gather the eggs every day, the hens are less apt to sit on them. Sometimes their maternal instincts kick in and they will sit on the eggs. When that happens you can just reach underneath and pull the eggs out. They may peck at your hand, but it doesn't hurt.
sit on the eggs
Sure! The only reason to have a rooster is to have chicks but any hen past 7 months will lay eggs!
Yes.yep
No.
Hens will not sit on eggs unless they are "broody" - which is when they are actively attempting to incubate a nest. Hens will not just sit on every egg they lay.
Yes, but they wont be fertile. Hen turkeys lay eggs in the spring with or without the tom.
