So, I just returned from a couple day trip and went to check on my 2 hens before I went to bed, and found one of them on the perch, and the other in a nest box. I picked her up out of the box and noticed that her stomach has a completely exposed bald spot. When I set her down, she just layed there for a few minutes with her wings hanging on the ground, but then she started her normal feather cleaning ritual, and seemed to be ok. So I thought that maybe she is just moulting and was in the nest to stay warm. But after reading a little on here, i'm starting to think that maybe she is broody. I am just nervous about anything new and different with them after losing my other girl last month. And I am suprised that she would lost that many feathers in 2 days, but maybe it is normal? They are buff orpingtons, a little over a year old. What do you guys think? Thank you!!
