Button chicks eating bedding?!

[GrimApatheia]

Hi all, the title says it all. My button babies are about 4-5 days old. I started them out on paper towels and shelf liner, then gave them some kaytee carefresh paper bedding (the natural brown kind). They love it, the only thing is.. They’re eating it!!! Not in heaps, just a few pieces so I’ve seen, but I still worry. Is this lethal?? Should I switch them back??

As long as they're eating plenty of their food, they should be fine.
