i have a year old splash (?) Wyandotte. I've had her for about a month. She's had this lump on her cheek the whole time. It's the same temperature as the rest of her head/face. It's relatively hard. It doesn't seem to cause her any discomfort. It doesn't seem to change size. I had all my birds on tetracycline for a week, then oxytetracycline for an additional week for a respiratory thing. It didn't affect the lump, so I don't think it's an infection. Any ideas?
