I'm sorry.
about 20 yrs ago I kept chickens and had no one to get advice from other than the feed store. I didn't do anything to keep them cool, they had a barn to go in but it was just as hot in there as it was outside. I never gave them DE or wormed them or anything like that. I gave them layer mash from the feed store (after medicated starter when they were little) and they had a pen they ran around in which wasn't secure (it was made from chicken wire and open on top). They were locked in at night in the barn but otherwise ran all around the pen during the day. I only gave them fresh water when their 5 gallon waterer was empty, and just barely rinsed it in between. I filled the 25 lb feeder and when it was empty, filled it again. Threw straw on the cement floor for bedding and probably changed it once every few months at most. I put a heat lamp in when they were babies but not for more than a couple of weeks and didn't have light in there other than the heat lamp (which was a white bulb). I never had the first problem with them. I wonder if I was just lucky.
