Hoping you can give us some insight. We have 10 back yard chickens(Buff Orpintons) raised for chicks form the local Southern States. Now mature and have been laying for several months. No rooster. Life style is pretty much free range and they coup themselves up and we close them in for the night. Now, for the past 2 weeks or so, we have one chicken that has been sleeping in the hay shed on a bail of hay. We even have to chase her out during the day. No eggs seen. At first we thought she might be egg bound, but after several exams could not feel anything. It also seams to us that if she was bound or otherwise sick she would probably be dead by now. When we do chase her out she will puff up at first but after that she seams to act normal. Could she be nesting? And confused? Any ideas would be appreciated.
