one of the chicks has some blue feathers on its belly and tail just like its dad so i am assuming this is a yellowface type 2. once this pair is done with the third clutch i will give them a break and pair the cock with a blue series to confirm this.
please give expert opinion about the chick's mutation.
here are some pictures of the parents and the baby with blue feathers
The chick and it's parents are all dominant pieds. Not sure if the chick is a type 2 yellow face or a green with 1 or 2 dark factors. Sometimes green birds look slightly blue when the feathers first appear. You should be able to tell in a few days whether it is really blue or just dark green or olive with a blue tinge
