How critical is the percent of protein in chickens that free range for at least several hours almost every day? At this point in time, I'm thinking of free ranging during school hours so the birds are out from (guessing, I don't know school schedule yet) 8:30 to 2:30 Monday through Friday, plus other times that the kids aren't outside playing unsupervised. I would imagine that if the percent is too high, they'll eat more plants and if it's too low, they'll eat more bugs? How much less purchased feed does a free range consume? I read that a free ranged chicken will eat 30% calories from grass, but these wouldn't be full time free ranged until the kids are used to being around birds. Can I use bug infested grains to make my own bird food to supplement the free range time? I've seen a ton of feed recipes, so I know you can make your own, but I don't know about the buggy grain. I can't SEE why there would be problems. I know I use feed to lure them back inside, but if keep food in the barn during the day, will they eat too much grain and not enough foraged food?
