This one is a long shot possible het pied. Years from having her ready to put that to the test but I have little doubt she'll prove het pied.
This next one I think is caused by egg stress. The possible het pied father of the first one is one of several possible fathers for this 2nd one but other than the ringer she doesn't really have a het pied belly.
I've decided not to even keep this 2nd one so I'll never know if she proves to be anything genetic but I don't think it's likely she is.
