Ok, back to the mites question. So my jubilee orps look great. no issues. but i did find a BLRW with an eye swollen shut and a couple of chickens looking like this BLRW above. Is that due to mites? This one is by far the worst looking. Or is this just adolescence? I dusted the orps and the coop but didn't get to all the chickens mostly because of time. I can't find any evidence of eggs or anything. I haven't gotten any bites. All the pictures i have looked at there seems to be clear evidence of mites so I'm struggling to know if I should be going on a mite rampage...
Help?
