That's an adorable photo!
I don't "let" my chickens in the house, but every now and again, one or two manage to find the kitchen/back door screen open because one of my dogs has nosed it open to come in or go out, and it didn't shut all the way behind 'em.
Molly, my BA is the most frequent visitor. The last time, she wandered into the guest bedroom while I was outside and I didn't know she was in the house. I was sitting at my computer when she saunters out of the guest room, comes to a stop parallel to my chair, and said, "Bok."
Just one syllable. "Bok."
I looked at her, startled, and blurted, "How long have you been in here?" Then I glared at the dogs on the sofa, who were both sitting up, watching. Normally, Dooley barks at chickens in the house. Not this time. I guess HIS issue is chickens eating out of his bowl.
Molly said, calmly, "Bok bok" and took a couple more steps before I picked her up. She was quite calm, no struggling, just a few rapid Boks of mild complaint, as I took her outside.
