We built the chickens a nice coop and a nice addition to their coop (in my opinion) but they're actively working to destroy it. It was built on dirt. The chickens absolutely love to dig up the foundation blocks of the coop. They love one foundation block so much the coop is starting to list to one side (sorry it's dark out so early here, look at the white top trim you can see the left side listing): And here's what they're doing to the foundation: We've tried filling the holes back in with dirt. Seems like that is a great excuse for a chicken to dig it up even more... FRESH DIRT! Then we tried putting a 50 lb bag of landscape "erosion control" rocks down next to the worst foundation block after adding dirt thinking that would help. Except... somehow the rocks have disappeared and the digging has continued. It didn't take long, maybe a few days? And these were pretty big stones. They flung them all over the place (as an aside: I can't WAIT to snow blow the run for the first time this season with all the extra small rocks to fling! Thanks, girls!). The girls also have a covered turtle sandbox with all kinds of fantastic dust bathing goodies in it and they love it. Except they continue to dig and dust bathe under the coop. So... what do you guys do? What works? The permanent solution I can think of is to concrete around the foundation blocks, but I really don't want to do that. Thanks for any help.
