Can't seem to find much on this topic. I know the standard amount usually mentioned is 100-150g of feed per day for a fully grown large fowl chicken. I guess this would also help in egg-feed ratio. So which large fowl chickens are the heaviest eaters on a daily basis? I would guess: Jersey Giants? Orpingtons? wyandottes? Which are average eaters? RIR? Sussex? Which large fowls eat the least? Leghorn? Welsummer?
