I am not sure I would let my chickens in my house. No offense to people who do. It is just my Guinea's love to get on my picnic table, sit there a second, Poop and they leave. This is a constant form of entertainment for them and annoyance for me. I would not like a chicken or guinea to poop on my floor.
It looked like a short little visit, and then they went out, I didn't see any poop, and I was looking! Mine come into the back room once in a while, make a nest on some chair cushions, jump down, poop then leave. It doesn't bother me.
Gotta love Cleese man, did you notice he had a poster of "Fierce Creatures" up! Those chickens look plenty "FIERCE"!
Mine to an occasional walk through, but only when I forget to shut the door when they are free ranging, guess there still remember where they grew up & where "home" is!
