So my chickens are about 3 months old and I have been letting them free range in the day. At night I lock them in a barn stall. But it's gotten so they don't want to go home in the stall at night. It's the only time I feed them scratch! But there is a lot of tasty horse stuff outside too. Since I feed wheat hay, there's lot of wheat heads around, and the dropped horse pellets, not to mention all the things growing/living in the manure and ground. So, what should I do??? Eventually I would like them to free range 24/7 but they've barely figured out how to roost, so I don't feel they're safe enough at night yet. Ideas? Is this normal?
