If you've got medicated then I would use it. I have used both with no problem. Tractor Supply only seems to want to sell the medicated stuff. You for sure don't want hens eating the medicated stuff, or the chicks eating layer feed that has too much calcium.
I would say that you should put down some paper towels over your bedding for the first week. My first batch ended up eating a crap load of their pine chip bedding (it was really fine choped that didn't help the matter) and 3 of 26 died because of it. The first 4 days are the most important. If you can get them past that it seems like they are good to go.
