I've been trying to decipher what is going on with my 2 year old brown leghorn. She was found, upside down on the coop floor below roosts. She was helped up, hobbled off and I've isolated her in a crate for care. There was no blood, but she was walking over her long primary feathers on the droopy left side, tripping. I have been examining her and this is what I found? Very hard for me to get a photo with her, she's pretty docile but hates my camera! This is inside the left wing along primaries. I've been researching wings and feathers and I don't know. I've wrapped her wing lightly to her body. Is anyone familiar to what I'm looking at?
