Check both parents real close... sometimes they only have a few white primary coverts or alula and no white primaries.Yeah that pretty much is in line what I read. Good chance then momma is split and I'm not aware. The breeder didn't have too much info on history but momma doesn't have any white flight feathers as are common in splits. As days go by, it's quite appearent the chick will have a lot of white on the body. Curious how she comes out.
