Legally.... if the "law" doesn't come into the house, how would they know what she's keeping in there? I said no way would I ever have a chicken in the house, and a diaper for it? HA! I now have a small frizzled silkie/polish mutt roo living in my living room. He wasn't injured, but the others picked on him so he wasn't eating enough. I found him in the tractor run one morning laying on his side and being stepped on by his flock-mates. I brought him inside to die in peace (he looked THAT bad). Gave him vitamin water by dropper and fed him high protein game bird food. Now over a month later... his flock mates will not accept him back. So...... I have a house chicken, a house rooster even. I've been looking up patterns for chicken diapers. I have to work on his habitat still. I do take him outside everyday to free range with the others and bring him back in nightly.
