Hi all. For those chickeneers more experienced than I, does this (first two pics) look like an abscess or a tumor? Backstory: 18 week old (today) Faverolles pullet. Last Thursday I found her pecking a small lump on the back of her neck (last picture). I brought her in, pulled the feathers, lanced the lump but nothing happened, and kept her in for a day. Packed it with sugar, sprayed with blu-kote, she seemed plucky and fine the whole time and stopped being interested in the lump so I turned her back out with the flock. Checked her every couple days and the lump didn't do anything. Fast forward to today, I checked her before I left but sometime between about 11AM and 3PM she started pecking this lump. The lump is easily twice the size since I last looked at her (Monday?). I had thought maybe it was a feather cyst/abscess but this doesn't look like an abscess to me. It seems more like a tumor (plus with how fast it's grown) as this isn't pus or infection, it's tissue. However, I don't have experience with abscess in chickens so I hope I'm wrong because if it's a tumor, I'm inclined to think it will kill her even if I heal the wound. Anyone have any similar experience? Tell tale symptoms of tumor vs. abscess? Online research mostly shows internal chicken tumors, not big lumps like this. She is in a crate, the wound is cleaned out, packed with sugardine, wrapped up, she's had nutridrench droppered into her and has drank water on her own but was not interested in food. Otherwise seemed only slightly less plucky than her usual self. I am fine to keep dressing the wound and getting her back on the road, but if this looks like a tumor to you, and it would be best to cull her, I would rather know sooner than later so she doesn't suffer.
