Is this a tumor or some type of disease?

She has a viral infection that causes tumors. There is no cure. Do not listen to that man, it is not cholera or typhus. When the birds have typhus, the first sign is their wings fall down and they get droopy. Then their poop gets greenish- yellow. If you only have one or few birds and they are very pressious to you you can save them through antibiotics and force- feeding them garlic. I saved a turkey like this. The mortality is over 50 %. But your bird seems to have the virus that causes tumours. I would not eat such a bird. Just in case...So "culling" may not be a good idea if you do not intend to serve the bird to people that are not related to you. If you cull her anyway, at least find someone who you may not necessarily be fond of and serve him a nice peace of fresh home made chicken...
