I went out to give the chickens bananas and notice my EE, Purdy, had feathers sticking up on the back of her neck on the right side right below her head. I picked her up and moved the feathers away and there is a giant scab. She didn't have this yesterday! There is a blob of what looks like blood but it's very small. Is it possilbe for her to get hurt and it turn into a scab this fast? Could it be from my rooster? There's no feathers missing so I kinda think it can't be from the rooster because he's a feather yanker. What should I do?
