I have a 19 week old Delaware roo (and his sister who is not laying yet) in with 4 BO girls who are all laying. He has been regularly breeding the Buff Orp girls so I decided to throw a few eggs in the 'bator with my wife's Polish eggs to see if he was fertile. Should these develop, what type colorations might I expect? I have experimented with the "chicken color calculator" but I am not sure what a Delaware is classified as. Not a biggy, just more curious than anything. Thanks in advance!!
