My ducklings are about a week and a half old and I had them on towels before introducing pine shavings. Today when I put in pine shavings as their bedding they became obsessed with eating it. I’ve heard some say that they’ll stop but they seem to enjoy eating the shavings and I don’t see them stopping anytime soon. Any solution to teaching them that the pine shavings aren’t food? I’m really worried they’ll choke or get clogged up from how much they’ve eaten so for now I’ve put towels over the shavings while I figure out what to do.
