Are you sure it was rats and not large mice?
Not trying to be patronizing.. a lot of people can’t tell.
I would guess they’re just enjoying the cozy shed with all its hiding spots and a belly full of chicken scratch every night.
Nahhh, you don’t sound patronizing haha that is a good point but I am pretty positive it was a rat cause it was HUGE and definitely bigger than a chipmunk! Smaller than a squirrel but definitely much bigger than a chipmunk (and some of our chipmunks are seriously huge!) or mouse. And had a long, naked tail and was huge and fat or at least good size. And it was out in the open for a while (the run is 12 feet long) and didn’t seem in too much of a hurry, just trotting along, then dive into the tall grass/woods/bush behind the run so saw it pretty clearly. But I guess it could have been a mouse. Idk.
But I’ve seen mice outside too (they’re usually in the stumps or wood pile though), voles/moles, chipmunks, squirrels, and a couple rats up close in the city (that was REALLY gross!

) so I’m pretty sure it was a rat but I was also on the other side of the run so at least 6, 8 feet away, so can’t be 100% certain but if it was a mouse I think I would be a little concerned I have GMO mice because this thing was seriously HUGE!!

Hmm that’s true. The other shed I organized a while ago and have most things in buckets or bins but there is a bag of gardening stuff in there and an empty feed back and everything’s stacked kinda chaotic and the two feed bins are next to each other so there’s a nice little gap along the back wall that makes a perfect path for a rat, mouse, or chipmunk! Hidden and private. So I think I will have to take everything out, redo it, and also maybe push everything directly up against the wall and eliminate the path. Then for the other shed I will just get rid of it I think because it’s just collecting stuff I don’t need. Definitely don’t need all those bowls and waterers. There’s also some bucket feeders in there I made awhile ago (they didn’t like it so I gave up) so maybe I should switch to those and cap them at night?
