Here are the two chicks. The younger chick really looks like it's going to be green
!!! I've double checked my books and am 100% certain this hen layed the egg from which this chick hatched! The pair is housed separately in a breeding cage and this is their second round. If it were their first round, I would suspect that she had been bred by another male prior to being placed in the breeding cage with her mate. Has anyone else ever experienced an impossibility like this? I guess it could be a random mutation but I assume this is very unusual. I'll keep you posted as the chicks continue to feather out.
