That depends on if one parent is SF or DF grey. If SF grey, then the breeder should get a combo of green and SF grey chicks. If the parent is DF grey, then all chicks will be SF grey.
The breeder can't guarantee a chick is split ino unless one parent *is* ino. If the father is split ino, then only males will be able to pick up the split ino gene, but it's a 50% chance that a male offspring will be split ino.... which means that the pair should also be able to throw ino offspring.... which means the chicks would be female and could be ino or SF grey ino.
