One of my silkies has been staying inside the coop. Yesterday afternoon she spent most of the time inside. I thought she may be trying to lay an egg. Another one went in with her and later came out. I checked and removed an egg. This morning she refused to come out again. I removed 2 eggs and brought her out. She ate for awhile and the next time I checked she is back inside. Eventually , I removed 2 more eggs but she would not leave her spot. I took her inside and checked her all over. Could not find anything wrong. Put her back out with the others and she acts fine, but check on her later and she inside again nesting. This time there are no eggs. Is she just being broody? Is this normal behavior? She gets picked on alot and is usually the last chicken to go in the coop.
