Thanks Beer Can, I had thought of keeping back one hen for cross breeding with my Sweet Grass that I got from Porters , but unsure if I want the added bird as the Ones from Porters are well adapted to living outside even in our winters .......I do house them , but given the chance they seem to prefer roosting in the elm tree by the coop .Once they get bigger I know they ( toms) are to heavy to breed and artificial breeding is a thing you have to do if you want to have pure ones ................decisions
