Yeah, this is a project for me tomorrow too. I have two runs that I can cover over to prevent any wild bird contamination. My main flock is allowed out into a yard during the day, but they're normally in their shed until I get back from work at 1/2ish...since it gets dark so early now, it won't do them much harm to stay inside the whole time I guess.
Not ideal....but more ideal than catching avian flu!
