If you had several different breeds but could only keep one rooster what would it be? What would be the best type to be breed with the mixed flock? Obviously I would have a few of the pullets be the same breed so that I could get pure bred birds as well as mixed ones. Is this a dumb question??? I cant figure out what i want my roo to be, I have an ee roo now but I wont keep him around forever. I weas thinking a Rooster that carried the blue egg gene (not sure if myy EE does since he is mixed) would that mean any of its offspring could infact lay blue eggs if it got that gene passed down?
