This is my first year with meat chickens (cornish cross). I have 26 of them and also 6 duel purpose birds in the coop. They are eating about 50 pounds of feed a week and I buy the feed from the local grain elevator for $80 per 300 pounds. That is the highest protein broiler mix they make. It seems like a lot compared to what I can buy chicken at the store for, I love haveing chickens but I am in it mostly for the cheap meat. Is there a better way? Do they need less protein mix when the get closer to butcher? Should I build a run so they can eat bugs before getting more meat bread chicks? My duel purpose and egg layers I free range but I am afraid if I let the cornish cross's out they won't go back in and predators will get them. Any tips and suggestions are apreciated.
