We have 11 chickens, 2 Rhode Island Reds, 2 Phoenix, 2 Americaunas, 2 Buff Orpingtons, 1 Black Star, 1 Black Copper Maran, 1 Mixed. All of them have molted except 2, which I know are young. My original Black Star, Americaunas, Phoenix we have had for over a year and they were about six months when we got them, supposedly. We added the rest about 4 months ago. During the summer they slowed down alot and we figured it was too hot, in Florida, and they would pick back up when it cooled off. Now it is cool and has been for weeks. What would make them just stop laying? The Rhode Islands, Buffs and Black Star are supposed to be excellent layers, and the black star always has been until now. Are they alot older than what we were told? We have one black copper maran (Spelling?) that we got when she was really young. About 10 weeks ago she started laying and we were getting an egg almost everyday, now for the last two weeks or so, nothing. Is something wrong with her? They are in a large coop and are let out daily in their very large run. They are fed high protein pellets and some chicken scratch, always fresh water and we give them some greens, but not alot. Any help would be greatly appreciated.
