They're very content, though they will escape into the yard at any time. And from the yard they'll escape into the great yonder if a gate gets open. So take that how you will.
Guess mine are crazy,we let them out every afternoon for a bit of supervised ranging but they "escape" back into the run if given the option, probably because they're so used to being in there that it's scary being outside. The few times I had a bird fly out pre-netting install, they just kept walking around the run, trying to figure out how to get back in.
