I have a black australorp who is 3+ years old and has developed a lump just under her eye. She was treated about 6 months ago with doxy for a respiratory infection. Besides the swollen lump she is active and feeding, like there is nothing wrong. I want to know if anyone knows what causes this, and if I should be concerned about flock health.
Any help would be greatly appreciated!
