A friend of mine has a few chicks she hatched from her bator. They all hatched late (2,3,4 days late) and then they didnt hatch..she actually had to hatch them. (Her temps were off but she has it fixed now).They were doing fine at first but then one by one they would start panting and then lay down and die. 3 so far has done this. What could be causing this? I really need to know because she has some of my eggs over there cause I ran out of room in my bator. I dont want to bring the chicks home when they hatch ( due to hatch today)if the others have a disease of some sort. They are hatching in the same bator as the dying ones. PS: the temp in her brooder is NOT to hot. I thought that they might be getting to hot but her temp is fine and they have plenty of room to get away from the heat. She does have them on puppy pee pads, I dont know if that has anything to do with it.
