Hen who can't seem to stand and puffy

Do you know how the predators got in? I don't trust chicken wire of any gauge, it's too easy to rip through it. If you can replace that with hardware cloth, or roof it, that would be more secure. Some predators will dig under, so a buried apron of hardware cloth can stop that. I have also buried concrete blocks (I had extras that needed to go away) around my perimeter in places, to stop digging. Most predators will dig one hole, and if they are stopped they move along as long as they aren't successful. Many predators will go over fence like it's not even there, foxes and martins or weasels can be extremely clever getting in and will come back. Many predators will keep coming back once they've had success, so it's important to get it secure.

Nope, there's no holes anywhere. We've had this coop up for nearly 11 years, never no issues.
