I have several eggs in the incubator & several that have hatched. I had one chick that hatched fine & by itself, but was breathing really heavy the whole time. When she fluffed out I put her in the brooder, but she died the next day. Anyone have any ideas as to why this chick might've died? I know it's a long shot but i thought someone might have had the same experience & figured it out. Thanks in advance.
