Last night we found out 2.5 year old olive egger deceased in the nest box with what appeared to be a complete prolapse of her vent. She had been dealing with what I thought was vent gleet for a few weeks, and hasn't laid in a few months. I could feel no eggs in her. She was eating again and acting normally except for the last few days she would hide when I would bring fresh veggies out and not try and eat with the flock. She was the head of the flock prior to this. The other girls werent bullying her. Any ideas on what could have been going on? I have one other girls who had a partial prolapse thati got back in and she still hasn't laid either but seems to be ok. I don't wanna lose another girl. They are my first flock. We have 11 girls left. All on Kalmbach layer 17% protein, free fed oyster shells, and fresh fruit and veggies a few times a week and meal worms for extra protein. Any advice would be appreciated.
