My husband noticed a gap in the mesh and didn't fix it or let me know, so we woke up this morning, we woke up to one trampled chicken and one muscovy duck with a small bloody spot on his side where I assume somebody tried to take a bite. Other than a few splotches of blood on the bedding, though, there was no more evidence of violence. We'll do a head count later on after we get home (we had to rush out to a birthday party).
