I have read on here numerous times how some member's chickens actually roost and prefer to stay in the goat house. I would say that it should be fine, as long as your goats can't destroy the chicken house and cannot get into the chicken food. My goats and chickens get along great, but the goats are not allowed access to the chicken area. And goats LOVE chicken food. My goats escaped and knocked over my chicken feed barrel, eating half a 20lbs bag of layer feed and almost all their cracked corn! I was not happy to come home from vacation to see that!!!! I'm lucky none of them bloated. My goats, as are many, can be destructive, so just make sure that their isn't anything they can destroy. But as for getting along, I would imagine they would be fine.
Good luck!
