I have a hen that has no eggs but is broody. I have the fake brown eggs I put in the nest and the hen has starting setting the eggs. She won't come out unless I get her out and she won't be out in the yard long before she finds her way back to the nest. I took one of the fake eggs out and put in on the ground to see what she would do and she sat on it. Do I need to take the fake eggs out so she will eat and scratch around?
