Over 4 weeks ago, one of my 2yo Golden comet hens presented with a very large swelling/hard mass underneath. She could barely walk and could not reach the feeder or waterer. This went on for a week. I feed/waterer her as I could. I felt inside her duct canal with a finger, and there was not an egg present. Her mass was below the canal. It was hard, not squishy. I ruled out water belly and impacted egg, because I thought if it were an egg, I'd have felt it with my finger in the canal. The mass went away about 2 weeks ago, but she was left weak and barely about to move. The other hens had tried to kill her so I separated her, hoping for a recovery. My flock is 20. It has been a week now and she is slowly making a little progress each day. She barely moves around still, but will eat and drink, moving very slowly. Her comb which was drooped and very pale is now more red and a little perky. I see this as a sign of getting healthy. She shakes her head suddenly at times. Any idea what is/was wrong with her? Thanks.
