I marked pullets who were fast feathering in my line #2 birds. The 2 cockerels were slow feathering.
Line #1, Negan, is fast feathering.
When the time comes to breed, my plan is to eventually produce this trait for sexing.
Ok here how you can breed FFT and SFT from your existing flock . forget about other fault ,here we are only talking about the feathering gene for future chicks sexing .
Step one = year one = Negan FFT X pullets line #1 SFT = F1 mostly fast feathering type ,because we don t know what they are hiding . we only keep fast feathering cockerels from this pairing .
Cockerels line #2 SFT will be bred to Slow feathering type pullets regardless odd of the line .= we get F1 SFT pullets and cockerels .not all but high percentage I think . we only keep SFT pullets from this pairing .
now we have .F1 FFT cockerels from Negan s pairing and we has F1 SFT pullets from Cockerels line #1 pairing .
Step 2= year 2 = we pair the 2 best F1 FFT cockerel { Negan } to the best F1 pullets { Cockerels #1 } = we will F2 FFT pullets and F2 SFT cockerels .they can be sexed at hatch .
chooks man
