My chicken which is about one year old is limping and has a very bloody cone. She was fine yesterday but then i realised that she wasn't coming for her breakfast. I went out this morning and i went up to see if she was ok but then i found her in the hedge in with a lot of blood on her neck and on her cone. I thought that she had been attacked by a fox but then there was no wounds on her . Please help!! What do i do?
