Chooks! Thx. For the great information! My chicken has a huge growth On her back like between her wings. It’s a huge tumor looking thing and it’s gotten bigger. We’ve had her on antibiotics for over a week with no changes yet of the tumor? And it does ooze alittle. She still has an appetite. She rolled a lot in the dirt today more than normal. She usually lays one egg a day but she hasn’t been since she got this lump lump? Any advice I would surely appreciate it very very much! Thank you, Tracy
