Only new chicks, and only for a short time until I move them out to the coop, to the brooder section. In warm weather, they go right out if they're purchased chicks, if I hatch them in the 'bator they go out to the coop brooder at day 2 or 3.
I once worked with a woman who had a silkie that rode inside her leather jacket when she went out on her motorcycle. Her silkie lived in the house with her, and a couple of times she brought her to work with her. The boss got wind of it (not from me, I thought it was funny) and made her stop.
I have 3 hens that, when they get the chance, will sneak in the kitchen door to steal dog food. My dogs, (one sheep dog, one funny basset mix, 2 lab mixes) are trained not to bother the birds, but I run them back out anyway, so they don't poop all over, or fly up and knock things over. Several others will come in as well, but those three make a habit of it.
