The bedding is important to destroy because it will be filled with oocysts. You don't want that going into your general soil.
Good luck with them. (And I'd complain to Tractor Supply).

I doubt the chicks are "clear." The meds simply reduce the load, hopefully to minimal. Once the series is done, they *should* be fine. However, the cysts are in the litter, so you need to completely destroy that litter, like burn it. Don't dump it on your garden.
Your older birds should already...
