Normally she would come running at the sound me coming into the backyard now she docent move out of the nesting box. If I try to remove her from the box she makes some noise but I can get her. Iplace her outside where she will walk fine and do normal chicken things only to go back into the box. This has only been happening the last couple of days and Im not sure why. She is a silky which I hatched and raised and lives with one other chicken, a Rode Island Red. I don't have a Rooster however a couple houses down there is soon that's been quite loud lately. She does give eggs but not consistently, i haven't received an egg from her in about 3 weeks. Is it due to the recent cold weather? Is she clucky?
