So i went out and turned on the heat light for my chickens everyone was fine. Then I ran back out to check for eggs (they freeze is they stay out all night) and i noticed some blood on a hens foot. Upon a closer look i didn't see anything right off, other than blood on her one wing. It was dry blood, but it looked like maybe she had some broken feathers on her wing. i tried to get a good look at it, but she was having none of it. Do feathers on the wing bleed? what should i do for it? I wonder what happened to her.
