Luckily I haven't had to deal with this issue yet (hopefully never will), but it seems to me that scaly legs and mites aren't a normal thing. I mean chickens didn't evolve having them. There wasn't someone to oil up their legs when they lived in the wild. There must be something that's creating conditions that increase the likelihood of bring scaly legs and mites on. Wouldn't it be better to eliminate conditions where scaly legs and mite are more likely to occur? I'm not sure what conditions those would be, so if anyone knows, I'd appreciate the knowledge. Also, I use DE. Would that help?
