My hen did not come home last night, we thought she might have become dinner. We found her this am, wrapped in some twine and stuck to a tree. We set her up under the tree the chickens like to be under, left out food and water where she could easily reach it. She can move around, but doesn't, possibly because of pain. She is now isolated in a large dog crate. One leg is injured. There is a large greyish lump under one toe on that leg. There was some blood on her leg when we found her, but no new blood. She has also laid an egg since then. What can I do for her????
