I have an arcauna roo, a cornish cross roo and a silkie roo....my hens are rirs, barreds, buffs and wyandottes....I think that the cornish is not getting the job done right so the other two roos are the daddys. How do I know what the chicks will be? I have six hatched out...two from RIR eggs and four I am not sure about...the first chick is yellow with dark stripes on head and back the other two are just yellow so far and the others seem darker in color but they are still wet in incubator. so what kind do I have ? do you all keep your roos and hens separate according to what breed you want? Is it true that they are what the roo is??? thanks for any and all advice...I just love bycs!!!
