I have an ameraucana hen that has been laying for a few weeks now. She's not regular like my sex links, but her main problem is that she doesn't seem to like laying in the nest box that is bedded with straw. She laid her first one outside in the run in the dirt. After that, she was pretty good with laying in the box. Then all of a sudden, one day she laid one in a dust pit right next to the back door. I've kept her and the rest of the flock locked in the coop for a few days and she did lay in the box with the rest of them. Then today she somehow broke out of the run and made her way to the house all by herself where she promptly laid her egg by the back door. I watched her today and while she tried to lay the egg, she kept picking up leaves and putting them on her back, near her tail. What was that about??
