Hello, I have 2 hens out of 21 birds that have scaley leg mites. I have treated them with vaseline twice. How many times and how often should I do this? Should I treat the other birds as well? Their legs look good in comparison but I wonder if they could just be less infested. Their skin is smooth with just a little bit of rough/dryness. Also, one of the ones that is infested.... I looked around her neck to see if I could see them. I didn't. How do you know what they look like? Also, the skin on her neck had a simular appearance of the skin on her legs. Dry, flakey and where the feathers attached to the skin, they were all powdery and cakey. I am still confused on how to treat the mites directly on the chicken other than vaseline on the legs and feet.
