Occasionally, a chicken will take advantage of an open screen door and wander into the kitchen, and from there, into the rest of the house when I'm busy elsewhere. (The dogs open the screen door but don't close it behind them. There IS a dog door, but it is at the front of the house in the sliding glass door off the guest room, not the back side where most of the chickens hang out. So far, none of the chickens have figured out the dog door....) The few that do this regularly stop to check out the dog food dish for some kibble, or maybe drink from the dog waterer just because it's there. After that, only the most intrepid hen - or duck! - wanders into the rest of the house. My kitchen, dining and living rooms are a "Great Room" configuration without dividing walls.
And I do brood chicks in the bathroom and do NOT cover the brooders. When the chicks get old enough to fly out of the bins, I cheer 'em on. The bathroom is very easy to clean so it's no big deal. I think it's cute to open the bathroom door and find a chick in the middle of the bath mat, giving me a look of "Whut?! I'm just checking things out!" Or, I'll come into the bathroom, all the chicks are in their brooders, but there's evidence of chick exploration on the toilet seat, or the edge of the sink, or in the shower stall. Once I surprised a chick inspecting its reflection in the chrome sink faucet.
But I don't have a House Chicken. I think the dogs would be miffed at having their domain invaded if I let a chicken watch TV with us.
