ya know, Brooks, years ago, that was my normal practice. I would use Sundays as my “No Feed Day”. I liked that practice. For some reason I stopped doing it. I’m thinking about starting it up again.
This gives the birds a chance to clean up any and all feed laying in the litter. It makes them work harder to find food. It saves on the yearly feed bill, and you are right, it does make it harder for mice and rats.
That’s a great idea, and one I recommend.
