I have a 16 month old golden comet that had a prolapsed oviduct (that went back in by itself) 3 weeks ago. I took her to the Vet the next week and they checked her over and said she was fine. Now she is passing what looks like a mixture of mostly yolk but no shell. I checked to see if any broken shells were in her and found none. I feed her Purina Layena and a small amount of vegetables from the garden (lettuce, tomato, squash). She has not stopped eating but stays on the perch in the same spot and when let out to free range comes back to the coop early and is very quiet. She closes her eyes often and occasionally shakes her head seeming lethargic. She is not herself as she has always been the curious one that hops up on my deck railing and peers through the kitchen window at me. She has not done this for some time. I know that heat can also work against them and it has been hot here but we have done the best we can to keep our birds cool. Has anyone had a similar experience with their hen(s)? I have been reading different posts out there and some say give them more calcium and some say antibiotics too. I really need to help this bird.
