Can chickens and goats be penned together?

I keep going back and forth on goats for our new place.  It's semi-rural and every now and then a mountain lion comes through and does some damage.  One of the neighbors lost a goat to one a few years ago.  I would only want pygmy goats, and they are obviously more vulnerable.  The chickens will of course be closed up in an enclosure overnight, and I figured the goats would have to go in one overnight as well.  Can I put them in the same enclosure, as long as it's big enough for the goats?  It would be fully enclosed and possibly electrified.

Looks like these people are raising chickens and goats together sucessfully:

Hmm, I notice in that picture that the fence it low enough that the chickens could fly out if they really felt threatened by the goats.  Also, looking at the smaller chicken coop and thinking about goats, I'm wondering if I would need to cement it into the ground to keep it from getting knocked over.  Having said that, maybe I could design the coop in such a way that it could also be a goat fun house.

My chickens get in with the goats every chance they get.

I've had chickens and goats together for years and have had no problems. The chickens love to lay their eggs in the hay feeder, and help themselves to the goats' water buckets and feed. Of course, goats will eat chicken feed too, so if you leave chicken feed out free choice you may want to have a way to keep it where the goats can't get it.
