I'm no really following you I dont guess, a crele is a crele.. a crel looking bird is not.. like Bob (who ever he is) said himself, it takes barred and partridge (bb red) the buff projects will just be a look a like and will never be a true crele though, period. I'm sorry if you dont understand that, but that's just the way it is.
Creles have a black breast, under carage and tail and saddles, you WILL NOT get that off a buff bird.
It's just like what they call crele in polish, they arent creles, the are usually barred gold laced. Look cool, but that is not the genetic make up of a crele.
I fully understand buffs have a sorts of stuff in them and fully understand what leakage is. BUT to get a crele like BOB's pic earlier, like he himself said, you will have to use a partridge, anything else will not be a real crele. If a non true breeding look a like is all you want, fine, but dont count on them being crele.
I'm not trying to be a pain, but I breed for countless colors every year in various breeds. It's what I do. I make colors in birds that they dont already exisit in, I enjoy it and it's fun. But the comment of many creles have been made off using buff x barred, well that's a 1 in a million deal there that will honestly just never happen.
When you make one that way, Lord please post a pic of it.
You'll be years ahead of the game if you focuc that project on lemon cuckoos and just get you some partridge orps from Bob to do the creles with. After all, if you go to all the trouble to make a new color, dont you at least want to know it will breed true in the end for you.
