I awoke this morning to a terrible sight. The heads of 3 of my two-month-old chicks were purple and blotchy and one was completely blind. The other 2 just half their head was purplish, and blind on that one side. The blind one was walking into walls and buildings head on so I am sure it was totally blind. At first I thought it was a disease or a fungus or something, but now I think it was frostbite. anyone heard of this? last night was about 28 degrees. The chicks are too big to be buried under their momma's feathers at night, so they leave their heads stick out. They don't put their head under their wing like adult chickens do to stay warm. Tonight, they look much better, all eyes are open and seeing, the purple has receded except around beaks and lower part of their head. (It was warmish today, up to 45). None of my other chickens have anything similar, and I believe it was frostbite and maybe their eyelids were stuck shut. I will bring them inside the house tonight, but wanted to share this dangerous situation and find out if anyone else has ever experienced this. They were born in October and they may be just too young to handle cold weather.
