I have a VERY large Brahma rooster - maybe a solid 8-10 pounds, he’s 9 months old. I’ve been treating him for scaly leg mites for months. We did the Vaseline on legs nightly (any bit of leg scales we could find was slathered in it - even between the feather) for three weeks or better, we cleaned the coop and scrubbed the roosts, we did ivermectin on the back of the neck - .5cc . It still didn’t go away. We treated once with castor oil as well, abs many epsom salt soaks. Recently we treated orally with ivermectin injectable .3cc and are due to treat again in a few more days. Then we will treat again two weeks from there. We have 13 chickens in a huge run - the original run was 8x10, and you can fit four of those in the addition. They’re on sand in the run, and straw in the coop. The coop is 8x4. They eat 20% all flock. What am I missing and why can’t I get rid of these? None of the hens have this issue. As an adult I’ve only kept clean legged birds. He also seems to have an ingrown feather on his foot. This poor guy is just the absolute best boy, and I don’t want to see him keep struggling with this. Someone else I talked to thought this might be more hormonal or maturity based, or due to the fact he’s feathered on his feet. It’s also worth mentioning that it has been super cold here for Alabama over the last couple of days - could that make the areas between his toes red like that?
