I have a hen that everytime I go into the coop at night she is in the same nestbox. The first night that I pulled her out she actually growled at me and just this night she cackled and squaked but no growling. I don't believe she is in there during the day just at night. So is this maybe a case where she can't find a spot on the roost as the chickens won't move over so she gets in there or could she possible be feeling a little motherly(broodiness)???
