selectively breeding genetic mutations for aesthetic purposes isn't exactly natural.
on topic: this is a very interesting theory. makes sense logically. i'm interested to hear input from a large scale breeder as well. haven't had my first clutch yet, and while i won't go as natural as maternal incubation, i don't think i'll be doing any cutting, at least not for the first clutch or two. just kinda seems like a spoiler to me. lol
