I have hawks as well so the run is fully enclosed. Our hawks are out all afternoon and gutsy as all get out.
Mind me asking what rodents have gotten in? I'm still working on predator proofing the run.
Rats. Rats. Rats. (I don't know if you've ever seen Rotatouille, but I am an eyelash shy of being that old lady at the start of the movie blasting away at rats with a shotgun).
We've picked up feed at night and placed in closed coop. They chewed through the SIDES of 3/4 plywood...midway. No idea how they hung and did that one.
We've placed feed at night in metal storage, locked. They then came out during the day, running across the yard, hoarding the feeders at will.
We've tried spring traps (they get very trap savvy, very quickly, taking the bait but leaving the trap unsprung).
I've tried every holistic deterrent available on the market including plaster balls with bird seed (supposed to swell in gut and kill them...we just had white rat poop everywhere).
What works in my area (notorious for heavy rat population with our mild wet winters)? POISON. Yep, I've sunk to poisoning the blighters. I get first generation blood thinning types that require several meals before they act to better protect cats and hawks that might get them. (Second generation is one bite kill neuro toxins that can kill another animal eating the rat).
And, I got a Rat Terrier mix (feral the first 8 months of life). He's got a kill record of about 30...yep 30...in the last 5 years.
Hawks come and go. Bird netting helps. Coons, use hardware cloth buried in dirt with raised coop and d-clip type locks. Coyotes have left us alone (thankfully). I think we are too enclosed, though they are in the neighborhood. Likewise oppossums have left us alone.
Squirrels can be bothersome in the fall as they face pile into the feeders to store for winter. The dog keeps most of them out of the yard.
But rats? Oiy. Some days I feel like I'm flooded with the darn things. We joke in our neighborhood that the trick is to worry them enough so they go to the neighbors for awhile.
Poison, and my rattie, alone have helped keep the numbers to at least a livable minimum.
