We just had a chicken just drop dead this morning for no reason. I have done some research on Foul Pox and we found out we have the pox and we have a pretty bad case of mites. I'm just wondering what did the poor chick die from? She had one of the less severe cases of the pox and we didn't find any mites on her, some of our roosters are COVERED in the giant pox and are doing alright. We've dusted our chickens before fair and we think we got the pox and mites AGAIN from the fair. Whats the worst the mites could do? Also I bought some DE and was wondering how to use it to get rid of the mites. (The store wasn't clear with the how) Thank you, Harli.
