My 5 year old buff orpington has just one swollen and bloody/scabby wattle. She doesn't show any other symptoms or seem to be bothered by it, but it is slowly growing. (this was taken a week ago and the wattle has doubled in size now) We do have bees in the same area as the chickens, so it could possibly be a bee sting. Although, I'm not sure if a sting would last a week. Any help will be appreciated.
