Hello, I have 21 adult birds and 6 day old chicks. The adults are infected with scaly leg mites. Egg production is low. One of the chickens has lost a lot of feathers on her wings. The quill remains in some cases but the little feathery part is missing. She looks terrible and now she is loosing feathers to the left and right of her tail. Pecking is not an issue, I spend a lot of time with them and she is high in the pecking order anyway. 2 or 3 other birds look like they are molting and 1 has lost feathers around her vent. I have a few questions...... Does SCALY LEG mite cause feather loss and affect the entire body of the bird? Could I have another type of infestation too? What can I paint the roosts with that I would have around the house? I was thinking vinegar or canola oil. Or maybe just paint to seal them in? I will remove all of the bedding (straw) and I will dust with Sevin. I will put DE in the nesting boxes and continue to put it in their dust bath areas. Can I put food grade DE in the nest where the day old chicks are? I will dust every adult bird from top to bottom with Sevin including the rooster. (gulp!) The following night I will vaseline all of their legs. Is it still safe to eat eggs while treating with sevin? I will repeat this whole process in 2 weeks. Anything I am missing? Thank you!
