as i remember, you have day olds in july/august. feed growers for about 8 weeks while free ranging them when off heat, the growers is to build a good frame/ bones, free range them till november feeding growers to get them in a night, i used to rattle the bucket of pellets and they came running.feed your fattening mix for 8 weeks up to xmas and restrict the birds movement.. the stags will put on more weight than the hens for the same amount of feed, you only get out what you put in, ie if you buy a heavy breed 25lb they will at more than a medium breed say 15lb, if you want to feed fatterners pellets ok but if not you feed barley/ wheat/ maize grits and field beans or tic beans, these beans are high protien 25%, permanent CLEAN water, the starter feeds may have medicine in them, a good free ranger is a norfolk black medium.
