In the goat area, yes. which is why we had to fix the coop so the goats would stop going into it. I haven't seen the chickens jump the fences. They've done a pretty good job at staying in their designated area on their own.
Our cochin's been refusing to leave the nesting boxes, even though there's no eggs in them. My daughter's been having to take her out once a day to make sure she eats/drinks.
I'm tempted to throw her in with the juvies for a few days to see if I can break that behavior.
Once my great pyr's are trained to protect the birds, and I can trust them to be careful, I'll let our birds have free range of the front part around our house. We have a lot of ant hills, and I'd be very grateful if the birds would... help control them.
