A lot of help please, I have bred Greens and Blues Princess for a few years, before the start of this breeding season I purchase a Lutino cock bird and put it with a Blue hen the lutino was out of( Lutino and White parents which I do not have ) and the Blue hen parents where both Blue, I have ended up with Green young ones. When asking the question why I was told that I could not get any thing other but Green. My question is there a simply formula to follow to get different colours. I have tried to read up on different sites but just get lost with the wording and how to go about it
