I switched them yesterday morning, and though they still ate some of their food. They ate a lot of small shavings. I layed a layer of paper towel on top for the night. I just took it off, but they are at it again. Scratching, pecking, and yes, they are eating some shavings. What do I do? I have 5 RIRs and 1 EE. Is it bad for them?
