I used that rodent repellent & they just bit through the bags.

Also tried the humane bucket traps & the squirrels knocked them over every morning to get to the peanut butter, so even if I got one, they didn’t stay in there by the time I got to them. Thinking of using mouse traps with Velcro stickers on the trap, attaching to one on the board above the laying boxes (so the chickens can’t get to them & when they trap a mouse, it won’t fall into the main coop area).
I think what ended up happening is the squirrels figured out how to get into the coop, but they had to trample all over the nests the mice were trying to live in, so I think they moved out. Haven’t seen any trace of poop or more damage from them.
But the rodents never caused my chickens to stop roosting in the coop.
That is a pretty tiny coop & run. Looks nice in the pictures, but when you see the dimensions/photos in the coop ad, it brings it into perspective.
We have 8 chickens in a 8x6ft coop (measured from inside - 7 ft tall at the highest point), with a 20x6.5ft hoop run (measured from inside). I’ll post a couple pictures.
You might consider extending your coop &/or the run. I am not a builder AT ALL, and it was easy to build our hoop run, covered in hardware cloth. No plans to work from… only measuring & cutting. Just need to build the frame on the ground, then 16ftx4ft cattle panel over in an arch so they can attach to the inside of the frame, and so it’s tall enough you can walk in it. Attach the cattle panels together with zip ties. Then lay the hardware cloth over that & fill in any gaps with hardware cloth. The hardest part was building a sturdy door at the end of the hoop, so we could clean the run & let them out to forage.
I hope you find a good solution!
