Well, I bet that is dried egg on her.
Have you ever applied egg whites to your face as a peel? I might be telling my age!
If you have, then think about how that feels when it dries - it becomes tight and is sort of just not comfy feeling. Couple that with egg yolk and you have a sticky (maybe waxy) feel on the skin and feathers. I still wonder if she thinks she's got something on her and she's creeping to avoid it.
I had a hen years ago that came out of the coop walking odd like she was trying to cautiously get out of something. Like when you walk into a huge spider web, you feel like it's clinging to you everywhere. I thought, oh goodness...she's sick. Nope. Someone had pooped a huge cecal poop on her back and it was stuck on but good! She was having none of it. Cecal poop does not come off very easy, she was not one that liked to be handled - we had a good time
