I'm beginning to hate Cornish X. They eat only commercial feed, at an alarming (and expensive) rate, and despite our good care, die with depressing frequency. (Our layers thrive under our care.) Might there be a regular breed that we could raise on grass as well as some feed, say, from early May, and have them big enough to slaughter by Labor Day or so? Plus, what grains or other feeds might we plant ourselves to feed our birds that would be good for them and also maybe less expensive?
