So I've been doing research, and I think I've found it. Both parents are natural coloured mallards, but he's different. He hatched out yellow instead of the brown with dark stripe like his siblings. Is he a silver Mallard or is this just a colour fault??
Could be the same, if they work the same as mallard. We bred two mallards. Got a yellow. He grew up with same colouring, just white lacing.
However could be a different breed as well
From what I know veins equals alive. You'll know if it's dead if it has a solid ring around it (blood ring). At 3 weeks you should be seeing movement from the chick as well
I put amaraucana. I would put Easter egger up next, but I would not go silkie, it might have just been where they came from, but I had way to many issues with them
Rarest we have would be Black Minorca, or corronation Sussex?? I don't know, are they rare?? I haven't seen many people with these breeds/colours of breeds
