So for two days we had a significance of rain here in Central Louisiana, and I noticed my 9 month old wet hen had huge bare patches on her body. I brought her inside to inspect her for injuries (we've recently had some attacks and stolen birds), but there were no injuries anywhere on her. The places where she is missing feathers is a healthy looking skin colored smooth area, but completely bare. Her chicken legs eerily resembled a store bought whole chicken. I didn't see any signs of irritation or lice, but I was mostly concentrating on looking for an injury. Today (two days later and dry chicken) I checked again, and I couldn't even find the bare patches. I'm sure they were there, and covered by fluff because feathers don't grow that fast....? Or do they? I swear she had fluff all over those previously bare legs. Again, checking for lice didn't occur to me, but I'm sure there were no egg clusters anywhere. I rarely deep clean the coop since we are using the deep litter method. I just rake the top layer under, and add new shavings every other week. I only sprinkle with a dust for mites and lice when I move the coop. I put it in the coop, and in the area where they dust bathe. Probably once every 8 weeks I actually move the coop, and start the litter method fresh again. I simply rake out the existing litter and compost into the yard, which the chickens LOVE. Is this adequate for the prevention of lice in our warm climate? Should I be worried that she has lice or mites rather than molting? Last question. I just bought, but haven't yet installed a Country Vet automatic flying insect and mosquito control kit. Does this combat lice and mites too?
