I have 6 chickens, two of which are new to my flock. They were rescued from a large poultry farm, they are not quite ready to lay still pretty young. They went through the pecking order and are now pretty much accepted into the flock. However, now one of my golden sex links who I have had for a while now is acting strange. She is normally very social, very curious and likes to stay with the flock now keeps to herself, barely leaves the run and quit taking treats. She was also a daily egg layer and I have not gotten an egg from her since she started acting like this, which is going on 5 days. Does anyone have any idea what might be wrong? I do live in south Texas and it's been VERY hot, could this have something to do with it... Or maybe the new chickens?
