I have this hen who for the last couple of days has been laying behind the doghouse. None of them have started laying eggs yet. They are around 5 1/2 months old. She was laying on a walnut most of the afternoon today back behind the doghouse, so we moved the dog house and put the walnut in their nesting boxes and she went in there and is sitting. She hardly makes any noise or moves while she is in there. Her belly feels different than the rest of the hens and her vent is almost a triangle shape unlike the other hens belly buttons. lol Do any of you have any idea what she is doing or what it could be? Whenever she stands she is all humped over almost humped back.
