So, I was wondering how my week-old chicks could make such a mess of their open food dish, until I caught them taking dust baths in it! 
I have a solution for the food, but know I'm wondering what to provide them for dust baths. I've read several posts, and opinions seemed mixed on what material to use or avoid. I thought I might use their grit as a short-term fix - since they don't seem inclined to eat it and have been turning up their noses at the treats I've offered - but I saw one post that said pet store grit shouldn't be used, which is what I have (fine-ground shells). Why would the pet store grit be problematic?
As always, your insight is appreciated!
