Yeah stay away from diapers, i have heard bad things about them too.
i had one hen who would come in and jump on the back on the couch and watch mythbusters with us, was very strange, she would come all the way into the house by herself then jump on the back on the couch and sit staring at the tv. She never pooped inside either. Very odd behaviour but i let her do her thing, think she needed a break from the rest of the flock.
My previous rooster would also lead the flock into the house when i was napping on weekend afternoons and crow at me while i tried to sleep. He would be stealthy until he got right to the couch, then crow at me.
