My 2 year old olive egger has prolapsed her vent for the second time in 3 weeks. I was able to get it back in last time and she seemed to be doing better but now this morning she is back to the same again. I gave calcium have been doing epsom baths. This time she seems more weak, her comb is purple toward the back and shes extremely thin. She was still walking around eating with the other girls so I thought everything was OK. Today i offered her blueberries and she wouldnt take any. She was drinking but nothing else. I havent seen her poop. I have a flock of 12 hens. They are on Kalmbach 17% layer feed, get oyster shells freely, and supplemented with fresh fruits and veggies. They are in a run not free range because of Hawks and predators. They have been laying thin shell eggs and odd shaped last few weeks. I have one other olive egger, Thyme, who is also not laying and has been straining periodically. She is not prolapsed has a bit of whitish drainage but not as bad shape. The other 10 seem fine. Im not sure what could be wrong. I've not had any health issues since getting them 2 years ago. Any advice greatly appreciated
