I have 13 hens and 2 roos, all between 8 and 10 weeks old. They've been outside for about three weeks in their coop / chicken yard. Last week I've started letting them wander in the human yard when I'm out gardening. They come charging out and love the grass and brush. Getting them back in the fenced area is a different story. I've tried getting the lead roo in first to see if everyone else would follow but no luck. I just bought some scratch and make a clucking noise and they come running when they're in their yard but when in my yard it doesn't seem to captivate them like when they're captive. Any suggestions on chicken round-up?
