Thanks everyone, for your replies! I'm sorry I haven't replied sooner, I worked a double shift yesterday, 8am-midnight as we are short handed at the correctional facility.
No one is pecking at her, she knows where the feed and water is and she snuggles to her "sister" pullet while they constantly talk to each other so she's being looked after when I'm not there. I think the raw spot is where it burst on her comb from the swelling. I've noticed that happens on dogs and cats, when there is too much swelling.
No seezing, no other symptoms, she hasn't slowed down any except for not able to see as fully as she normally does. I do have topical benedryl or 25 mg of benedryl so I'll start w/the topical.
CMV: I believe your hen passed out because benedryl makes most beings drowsy

I'll remove my girl while she's got benedryl in or on her because while she's sleeping, I don't want anyone to think she ripe for pecking on because she most likely won't wake up enough to move if they are curious about why she is just lying there.
No smell, no other signs, and the only insects so far since we have had a foggy, cold start to summer (still lots of ice in the Bering Sea and snow on the tundra), plus rain, are spiders so she may have had a bite from one of those.
Thanks so much again, everyone, she and her sister are hatched from my BLRW hens (only 3 of those) and a black EE roo because I do not have a BLRW roo. As a side note, I was trying to increase my flock of BLRW's but with the long distance and iffy weather, no luck so far w/viable eggs shipped so these two lil girls are special mutts to me. Thanks, Cheryl
