Our bantam "Special" jumped into my pickup and was waiting for me to take her to lumber yard. I dont know how you train a chicken to be potty trained in a house. Maybe someone knows how it could be done.
Hello and welcome to BYC! Maybe you should make her a diaper. I'm serious! Some clever people on here make their indoor chickens diapers. Search the forum for pics (use the search bar, top of the page)
