I have an interesting development in one of my nest boxes. Parents are a gray normal cock paired to a gray opaline spangle hen. They are on their second round and produced two gray normal chicks the first round. They are now feeding two second round chicks that are just beginning to feather. It looks like the older chick will be a gray spangle. Strangely, the younger chick appears to be developing pin feathers on its head and upper wings that are yellow instead of white. I understand that double factor type 1 yellow face birds will have white faces, but when paired to a non yellow face bird shouldn't these produce all yellow face chicks? How could I have one yellow face chick when the pair has produced three white faced chicks? Does this make any sense? Thanks for the help!
And I thought getting a white based bird out of two yellow faces was strange...
Curious to know what's caused this.
You know you might have too many budgies when you're not sure if you've remembered them all!

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.
