I've got a batch of celadon layers just coming into lay. Tonight as I was out topping up water I see one of the hens with what looks like a bloody mass hanging out of her vent.
Upon closer inspection, it's an egg that was most of the way out but somehow dried to the tissue of her vent, causing a partial prolapse as it pulled it out of the vent.
I prepared a soaking container and tried to gently dunk her but she thrashed around and stuck her face under the water a couple times.
The egg came loose pretty easily, I was surprised. Even more surprised when I gently pushed the tissue back into the vent and it went with no trouble and stayed. So hopefully it stays in. But now I'm going to have to watch to see that she didn't give herself pneumonia by inhaling water.
