Well I swear the 4 chickens I'm raising right now are the only ones I've ever had that don't love all sorts of treats. They are still young, and only roughly 8 weeks old, but I occasionally throw bits of lettuce, bread, carrot tops and other veggies I'm done with and they peck it once and move on. They also don't seem to be entirely interested in grubs, slugs and worms.. I tried giving them yogurt a while back and they didn't touch it so I mixed in some feed and they still weren't interested. I thought maybe I have too much feed available to them? But then chickens are fairly good about regulating feed and such. I mean they peck at everything and enjoy grass they get. I'm feeding them medicated start & grow still....By the way when can I stop feeding them start & grow and or medicated feed? Thanks!
