Is it just that beard & muff is not showing up in the birds that have the right other traits?
I see it on at least two of the females in the breeding pen you showed.
Muff/beard is a dominant trait, so if you breed two birds with clean faces you will get offspring with clean faces too. (I see...
True, to get the entire correct pattern in the F2 would require hatching large numbers of chicks, any way you do it.
I was suggesting that they select F2s for lavender and mottled (1 in 16). Then they would have have less genes in play as they work among those birds to fix e+ and barring.
And...
To get one of what?
If you just go for mottled + lavender, it should be 1 in 16.
So hatching 250 chicks should give you over a dozen of them.
If you are trying to get e+ instead of E, and barred instead of not-barred, and be picky about gender, of course your odds get worse very fast.
I think...
Sorry I'm a bit late to notice this thread.
I agree, that is the logical first step.
Yes.
No, that does not sound right to me.
For mottling: 1 in 4 birds should be mottled.
For lavender: 1 in 4 birds should be lavender.
For mottled AND lavender, it should be 1/4 of 1/4, which is 1 in 16...
