You need a nice hoop run attached to that thing. It's very nice though. My chickens have been out.
I noticed lots of foot prints around all the coops this morning. Not rabbits or cat for sure. Visited each coop except the one inside the fencing. I am not happy about that.

I've noticed a rabbit a couple of evenings. I usually have one under the wooden coop, but not the last couple of years.
I haven't seen any squirrels but I've been dealing with them, as they get in the coops. If they'd leave the chickens alone I'd leave them alone. They've chewed through far to many of my jugs of feed. I've tried to get replacements but have been unsuccessful. We no longer have cats.
