My 4 year old Americana hen has (what I believe to be) 1 red, swollen wattle. Her other wattle is unaffected. I haven't noticed any other symptoms and she seems to be acting normal. I did see her yawn several times yesterday, but I've kept an eye on her and haven't seen her yawn any more. Has anyone had this happen? I am not sure if I should be worried. Here is her normal wattle. Here is her swollen wattle.
