He has produced clutches for his former owner, with pied offspring, I have not yet bred him as this will be my first year breeding. I do not know if any of his offspring have high white sides like he does. I know the breeder I got him from pretty well, so it would be nothing to ask.
If I remember correctly the pastel poss het pied female I have is his offspring. My records state that she was from a het pied to a pastel het pied breeding that produced pied. I can't say for sure though if she was from one of his clutches or I just assumed such being that she came from the same breeder. She certainly has a similar look, but I have not noted that she has any extra white. She's at about 550g and honestly I haven't paid that much attention. I will grab her out for a few pictures when I get home if you would like.
Edit: Out of curiosity do all the babies you posted have tack markers?
