Taking a chinchilla out of it's "house"

I remember reading somewhere (I forget which website), that it's not good to take a chinchilla out of it's little house/hut thingie when it runs in there, because that's their "safe space". You should try to pick it up/get the chinchilla when it's not in its house/hut. Does anyone have an opinion of that?

When I come to get Mr. B out of his cage for playtime he always tries to hide in one of his 2 little huts. He does get pretty defensive when he's in his hut and I'm trying to catch him...
