Hey folks I have a ? I have some 5 week old white rock hens. I went out to check on them yesterday evening and one hen was dead laying on back with all feathers plucked . Didn't notice anything odd leading up to this . It was very hot maybe she died of heat stroke then they plucked her .Coop is in totally shaded area but little breeze and temps around 100 I put a fan on them today and added two more waters . As of today everyone seems happy and healthy . Any Thoughts?
