My broody Leghorn just hatched 6 eggs that I bought for her three weeks ago. The Polish Tophat egg appeared to have a Polish Tophat chick in it. But the 5 little brown Rhode Island Red eggs had a couple of surprises. Three of the eggs produced chicks that are some shade of red, but two of them produced gray chicks. I assume there was a mix-up which is fine with me, because you can't have too many types of chickens. However, one of the chick's eyes are closed, and I took him away from mama for about an hour to dry off and get a good breath. He looked squashed and on the verge of not making it. He just seemed weaker. He seems fine now (several hours later) and is back with mama. However, his eyes are still not open. Any ideas what could be wrong? Any ideas what breed these gray babies might be?
