A few weeks ago I'd been noticing poop in my chickens' feed. It only happened once or twice. I'd thought it was some wild bird's poop, so I just dumped the feed out and gave them some more uncontaminated feed. However, when my mom went to let the chickens out for me yesterday, she said a small black rat darted out the opening. In retrospect I haven't really cleaned the coop much in a long time, but I'll do that today. What should I do? Will the rat do any harm to my chickens? I want to set up a trap, but I'm afraid the chickens will step into it. How do I get rid of the rat? These are pet chickens and they really mean a lot to me.
