Wound under my hen’s ear

[Hilltop Flock]

I just noticed a wound under one of my hen’s ears. She is acting completely normally. I’m not sure when it happened. There is no dried blood on or around the wound but it’s lookin a little brownish... like dirt mixed with plasma maybe?

I’m guessing this is from a tussle with Mr. Rooster...

I have iodine on hand and can get other supplies. I need something like bluekote probably?

How would you treat this? Should I wrap it?

It looks deep, but the ear is in tact and I see a distinct barrier in the wound—it doesn’t look like it is going into the throat.
