I had no idea to separate them, this is my first time with broody hens and fertilized eggs!
One of the main reasons to separate broody hens is so the other hens cannot lay eggs in their nest.
Sometimes the eggs get broken as hens fuss over who gets to lay in it.
Sometimes the broody gets off, someone else sits on her nest, and the broody starts sitting on another nest-- then her eggs get cold when the layer is done.
But the most common problem is just from eggs being added to the nest each day: unless you are careful to take out the new eggs, they start developing too. Then the first chicks hatch, the hen comes off the nest to take care of them, and the eggs that are not yet ready to hatch are left cold and abandoned.
If everything seems fine, and if you check each day to remove the new eggs, then it's probably fine to leave the hens where they are. You can use a pencil or crayon to mark the eggs that are supposed to hatch, to make it easy to recognize the new ones.
If you try to move a broody hen, sometimes she will leave the eggs and try to go back to her old nest. If they seem fine now, I would probably just leave them.At night, Big Momma has 3 other hens that sleep in the coop she’s in total 4). Lil’ silkie momma is in a large coop with 11 others at night. Are they both okay to stay in their coops or should I move them? They seem to be doing okay but I want to be on the safe side.
In future, if a hen goes broody, you can try to move her before you give her eggs to hatch. Just let her have some fake eggs to sit on for a few days, until you know she's settled in the new place, and then give her the real ones to hatch. That way if she refuses to move, the only eggs getting cold are fake ones. (Only if a hen needs moving, of course. No reason to bother her if she's sitting in a good place.)
