Hope your girl with the prolapse is OK, she should be, she's a Warren!!
I have never had that happen to a hen, but I gather it is not uncommon. Now is the chance to show your girls what you are made of, they are SO easy to handle, and end up being your total slave.
We have had family dinners in the garden with the hens out in the summer, cooked extra spaghetti, as they will kill for it, and then had hysterics, when one or more of them has ended up with spaghetti boots, such is their excitement.
All for the future - great fun.
