Mother and father also attached. 

okay. What about this one. His mother is DEC, but father a green unknown. Could he be split for clear flight?

The mother is next to the normal blue. She was bought with a green male. When put to this blue normal, she had a dec white. I was told the dominant pied if they have a small mark on their head shows they can be split for recessive.  I am only repeating what the person who sold me said their heritage is.

ef and df dominants can never be clearflights , and not split at all ,  that does not exist

ask yourself this question , why do dutch pieds x recessive , black eyes and ef and df dominants x recessive not do you think ? same with a clearflight or clearflight born from a white black eye x recessive , why don't dutch pieds come out , mmm . the pi factors of dutch fur from the pied matter are the most difficult of all budgerigars, and there are very few in the world who understand this, not even judges. if you know the answer to my questions, feel free to answer but bitter few will answer, because they don't understand genetics for that you really have to have a high iq.

ef dominant out a dec you are a ******* lair , you talk nonsense
