Feel free to do your own research. Most people don't put day old chicks on any kind of loose bedding for safety reasons with their feet. Once they are a few days old (and start pooping way more) it's fine. Paper towel and puppy pads are great, newspaper is too slippery though.

Pine shavings are one of those things, it's pretty much ubiquitous. That doesn't mean it's the best choice or safest for the animals long-term. I'm not saying I'm a scientist and I've got proven hard facts for you, I just know that there is enough research available that has prompted some people to look at alternatives. If you feel like watching the video I linked above, it's really interesting! She has a lot of great information. I'm so glad I did, because I brooded our chicks on pine shavings in the past, and using the shredded paper this year I can tell immediately the difference in terms of dust. I'm a believer for that reason alone!
