I haven't seen any white in my Montanas but I do have a customer that bought a pair of split to Montanas tell me one of their chicks carries White. No biggie at this point but something to keep in contact with for updates. Seeing how it was outcrossed it is probably not related to the Progressive White gene.Oh it gets better said person has been selling montana lines that are popping out progressive white left and right. Had a hen go on me and was contacted by a few others this week about their own montanas from the same breeder going progressive white.
