Welcome To BYC
Can you post some photos?
If it's mites, your other hens may not have the same problem at this time - they may dust bath more or even have a stronger immune system - who knows - in some flocks you can have several birds with an infestation while others don't have any bugs on them at all.
How old is your OE - is she molting by any chance?
Sorry it has taken me so long to respond. My husband had a triple bypass heart procedure soon after I posted. My OE seems to be the only one effected. I don't see her being bullied. She still appears to be content and a good egg layer. I am applying elector psp today to the vent area. The crusts around ears & etc. has cleared up on its own. She was born in Aug. 2018. This occurred after she started laying.Welcome To BYC
