I am new on this site. I used to breed budgerigars as a kid and I'm thinking of getting into the show hobby. At the moment I am trying to get my head around how colours are typically bred.
I have read lot of vintage budgerigar books, the best being "The Cult of the Budgerigar" by W. Watmough. In this book he describes the practice of dipping into green. With this practice, a line of say skyeblues is maintained by outcrossing to light greens (split for blue) whenever colour or type start declining.
My main question is. Is it possible to breed a competitive line of show birds without keeping grey greens?
Grey greens seem to have better type and I can see how they can be used to improve other colours but I just don't like the colour and I suspect that they must be the hardest birds to sell to the public. I see cages full of grey green show culls at a local bird dealer who tells me he often has to give the things away.
Would it be possible to breed a line of lutinos without outcrossing to olive hens to maintain size?
If I kept albinos would I need to keep any other colours?
Dilutes look interesting. Would I need to keep normal/dilutes to maintain size and show type?
