I have 19- 8 week old RIRs 1 australorp(8 wks) 1 Jersey Giant(8wks) and 3- 12 week old jumbo cornish x rocks. Does it make any sense that they are eating over 50 pounds of feed a week? My 8 week olds are outside all day. Are those 3 darn jumbos eating all that feed? My daughter begged us to keep a couple of these hens when we were processing the others at 10 weeks. But if these birds are just big piggys, they'll have to go!!!
