So this is my first experience with chickens. I got 17 this Spring and they are almost 33 weeks old. They are allowed to free range anywhere on our ranch during the day and all march back into the coop at night. About a month ago I found one of my Buff Orpingtons nesting outside and wanting to sit on her eggs. So my husband and I took her and the 31 eggs back into the coop and put them in a nesting box. She was very mad at us and promptly got up and left. I haven't seen behavior since about anyone trying to nest on their eggs. Friday night I went to lock up my girls and the same chick was missing. I searched and finally found her yesterday morning on a nest. I haven't seen her get off of it at all. It is pretty chilly in MT right now with night time temps in the low 20's and daytime in the 40's. I set up a little shelter around her and put a towel over her last night. And yes, there is a rooster with them. Should I leave her outside or attempt to move her? Will she get up to eat & drink on her own? If she continues to nest on them, how long until they hatch? Any answers are appreciated!!
