Ok do you treat baby chicks the same as big chickens when it comes to mites I have never had any on my big ones and I got 4 new little ones and my silkie died last night on investigations she has some tiny white/clear mites and now the other three need treated. I feel so bad as its my falt she died since I havent looked for mites.This is my first chick to die my first loss. Oh how sad it was. And my one and only silkie. So now that I realize the problem the others need treated, I already called the feed store/hardware and they do not have poultry dust just 5% seven dust will that hurt 3 to 4 week old chicks.
