Deformed Egg in My Chicken

[DutchsCluckers]

The other day my neighbor was teaching me how to clip my flocks feathers. I was telling her that my Barred Rock was acting
real lethargic, sleeping on her feet and not moving much. We were both looking at her when she dropped a chickie bomb but we noticed something poking out of her. I grabbed a paper towel and while my neighbor held her I pulled out an egg that was open and looked like a flattened football. The next day she was acting a lot better but today she's still active but not interested in her chicken crack(cracked corn). Does anyone know what could cause this? My neighbor says it's probably age. I believe she is nearly five years old(I didn't raise her from a chick). I am really worried about her.

If the egg was broken she could develop egg yolk peritonits. If you can flush her vent out with weak white vinegar it may help. Make sure she is getting enough calcium in the form of crushed oyster shell or eggshells fed back.
