My chickens don't care if my five month old runs in and out of the coop/run with them. The problem is that they really shouldn't eat chicken food since most chicken feeds are made with animal by products. Goats are herbivores, but will eat chicken and cat/dog food which is bad for their rumens. I'm constantly keeping mine out of the coop. A little isn't bad, but goats really are sensitve animals. Most people think they can eat anything, but that is SO not the truth. They're pretty fragile. Not trying to scare you off, just do a little reseach. Mine got into the boxwoods and was sick for four days. He pulled through and has never touched them again. I had no idea what I was getting myself into when I got him. Then I started reading about them on the web and backyardherds.com and realized I was lucky thus far keeping him a live. I had him neutered and he's worth it. He makes me laugh daily even though I have to watch him like a toddler. The neighbors have lost three in five months. Just learn all you can because they are a blast. Mine is like a puppy, maybe worse. Lap goat? Seriously, he is!!!!
