Do you have mice in your coops? I did for the first time this year and I just about couldn't stand it! I was so creeped out and having a hard time going in there! I'm in the North, so we have to shut our coops up all winter and feed in there. I would open the door in the am, and the feeders would have mice in there eating before they would run off. They got so fat, they didn't run real fast. Ick! Here is how I got rid of them. It worked out for me that one of our barn cats "volunteered" (ok, I threw her in there) to spend her nights in the coop and now she has it cleared out, but she likes sleeping in there, so she continues to go there every night when I shut the coops up for the night. The chickens don't seem to mind her being there, either. I have a mix and my little silkies are in the part where the cat likes to be most. She doesn't bother the chickens at all. I really noticed a difference in feed, I'm buying much less and so now I am scared to know how many must have been there! Ugh, gives me the willys just to think about it! lol Anyway, just wondering how common this is to have a coop cat? It sure works well for me and I wish I had known of it sooner! The cat really appreciated being in a warmer bed than in the barn last winter!
