Hi. We got a chicken egg off a friend's neighbour and hatched it, the chicken is now almost 12 weeks; it had a large comb and wattle at 8 weeks and grew very quickly, however, it's stopped/slowed down now and we don't know what breed or gender it is. Any help would be greatly appreciated.
He's a mixed breed cockerel. I'm not sure what breeds could have gone into him (its very difficult to determine the parents of cross breeds), but he might have some Columbian Rock or Light Sussex in him.
