Hi skillful budgie breeders,
I had been sorting baby DF YF 2 skyblue normal spangle budgies and SF YF 2 cobalt normal spangle budgies all in juvenile plumages, but I had difficultlies in telling which are double factor yellow-faced type 2nd and single factor yellow-faced type 2nd, in juvenile plumages.
Father was SF YF 2 cobalt and mother was DF YF 2 skyblue, both parents are normal spangle.
I do not know how to tell DF YF 2 from SF YF 2 in juvenile plumages.
Can you please help me...
