I have 9 hens and 1 rooster living together in large coop and run. Normally I open the coop door first thing in the morning and they all come running out into the fresh air. Yesterday morning one of my hens, Belle, (a 28 week old RIR/Light Sussex X) was missing from the morning head count and I found her in one of the nesting boxes, I thought laying. She was missing at lunchtime too and she was still in the same nesting box and again at teatime. I felt under her and there was one, very warm egg under her. As I had no intention of letting them hatch their eggs I started to remove the egg but hadn't got the heart to take it from her and put it back. She was still there, with her egg today. I watched her for a while and she left the nesting box briefly to eat some food that I put out in the coop, (their food and water is normally in a covered part of the outside run). While she was out of the nesting box some of the other hens and the Rooster seemed to be picking on her giving her a peck as she went near. After about 5 minutes she returned to the nesting box.where she still was when I shut them in for the night. This leads me to a few questions. Why would the other birds start picking on her? would they have forgotten her if she's spent most of the last two or three days in the nesting box? I haven't seen her out in the coop drinking or eating, should I put food and water inside the coop too so that it is closer to hand for her? Will she continue to lay if she is broody? If I leave her with just one egg and she manages to hatch it I will end up with one chick of that age, if it hatches into the coop will the other birds accept it? Is a lone chick a good idea? If I put more eggs in with her would she accept them?
