Right now, I'm not sure what I have. I know something had dug into my compost. Could not catch it. Today my dogs noticed movement in the garden that is fenced in. Sure enough, there was a rat. It was chewing on some leaves. Seemed odd for a rat to be active during daytime. I live in a mostly, urban area. So, I'm guessing it is a Brown Rat. But, they are nocturnal. I don't know much about Woodrats. Plus, it seems odd for a Brown rat to be chewing on leaves. Right now, it seems they stay away from the chickens and their coop. I've checked all around the coop. Not a sign. Assuming they are Woodrats; do I need to do anything about it? I can secure the compost. The garden I can fix up. Will they leave the coop alone?
