I'd like to see breeding trials to determine if they're caramel + lav + hypo, or possibly just caramel lav. (Or something else.) It should be pretty easy to put a male with a caramel and a hypo lav, or an amber and a lav, etc, and that would give a very clear answer.
Whatever they are, given that several have hatched from the same line, they're almost surely reproducible and deserve a name.
"Peach Phase" suggests it's just a selectively bred variation.
Given the hatchling I saw, I think "peach" is about as close as any word can be... the only other things that come close would be "Caucasian" or "Nude" corns.
Peach Hypo suggests it's a hypo gene, so if you were going to use them together I'd think "Hypo Peach" would work better. This would also be nice if it turns out that they are Hypo Caramel Lavs, because then:
Caramel lavender = "peach"
Hypo caramel lavender = "hypo peach"
