Thank you folks for the info on ferrmented feed. Don't have any chicks yet, but will save the info for later. Going to try this on our big birds. We feed layer crumbles, scratch and some fresh veggies as treats. They love the core of sweet peppers. They go crazy for the seeds!.We have twenty birds, would it hurt them to give them a whole head of lettuce and let them have fun with it? When I have stale biscuits we toss a couple of them in the yard and they play keep-away, we call it chicken soccer.
