Oh, that's a fascinating trap idea!
I found a good way to trap mice, by the way: put your freshly made bone broth out on the floor with a piece of plastic wrap over the mason jar instead of a hard lid. Secure with a rubber band.
I had quite a surprise when I brought the broth in from the garage (aka, my large walkin refrigerator during cold weather). And the hole the mouse made in the plastic was no bigger than maybe a dime.
I found a glass gallon jug in my parent's attic one time that was full of mouse corpses, they must have smelled the mouse corpses and hopped in. I made a couple of batches of bone broth before I discovered that you could just buy organic bone broth at the store.
Ew. Yuck!
Yes, you can buy bone broth...but our budget is tight enough that I try to make as much as I can myself and it's a great use for the chicken thigh bones.
I was buying the bones and that got pretty pricey and I couldn't get organic bones. Making it was also messy, stinky and time consuming.
