My understanding, after a quick 10 min google search, is that Crele is barring + partridge. Please, somebody correct me if I'm wrong.
The thing is, OP, you're crossing barring with buff and nothing I've seen that had partridge. Thus, you will get a barred bird with gold or buff coloring mixed in. In other words, a gold barred bird. Without the partridge in this mix, there's no crele, its just barred.
Now, I'm not a geneticist, I'm not even a breeder. I haven't bred chickens, and I've only had my flock for 2 years. That said, I've tried very hard to learn the correct terminology, learn the correct characteristics and the terms for them, so I'm learning how to identify breeds as well as gender, and the right way to identify gender. This, even though I've gotten blasted on the BYC FB page for using proper terminology.
Its all learning... accepting information and absorbing it. Using proper terms, accepting the advice of those who have more experience and knowledge.
