So.... My coop is actually a pigeon coop turned rabbit hutch turned storage shed turned chicken coop. From its incarnation as a chicken coop, it's got this little shelf that the pigeons could use to get to their little exit/entry holes. The shelf is the highest point in the coop, and therefore a very lovely roost. They love it so much that I don't want to get rid of it, but it has a flaw. The chickens crap rather extensively on it, and so I'm scraping crap off every other day (I don't think it's healthy for them to roost in their crap -- correct me if I am wrong). Has anyone had this problem? How have you corrected it? I'm and and and and over the stupid thing.
