Okay.Here's why you're having trouble getting buff to come through.
Chickens who express buff need three key genes.
- The red gene
- The dilute gene
- Black restrictors
So the problem comes that in the first BO x BR outcross you create splits. Then breeding those together is your best chance of rejoining all 3 genes needed. If a bird has red but no dilute or black restricor, you get black barred with red leakage. A bird with red and dilute and barred will probably be black barred with maybe some buff leakage. Uniform buff would require a black restrictor gene but then there goes the black barring.
