This giant bumps came on suddenly and grew extremely fast, but they are not scabbing over, like I thought pox does. These bumps are all over any parts of her that are unfeathered-- her neck, face, and chest. (She's a naked-neck hen.) She is lethargic, uncoordinated, and is acting blind, although she has one eye that half-opens. She tries to eat, but is having trouble aiming at the food, so I've been tube-feeding her. She has been this way (bumps getting progressively larger) for about ten days. Someone suggested this might be lymphoma? she doesn't have any pox or lesions in her mouth.
