Chicken can't pass shell-less egg

[wendigo]

So we have this chicken that had some problems with eggs before. She's 1 year old and has been laying many normal eggs. But from time to time she becomes lethargic, walks slowly, retreats in the bushes and "fluffs up" her tail. She ends up squirting out an egg yolk and then returns to normal. She has another one of these days right now, but the problem is it's been almost 24 hours since the symptoms began and still she hasn't passed the yolk. I'm worried that something might be stuck in there. Is there anything I can do to help her?

We already give them calcium powder mixed with their feed so I think it might be something wrong with the system.

You can try to feel for an egg with a glove and lubricant--1-2 inches into the vent. If you feel an egg, stick her in a warm bath. She may be suffering from egg yolk peritonitis or internal laying, and there isn't a whole lot that can be done for it other than trying antibiotics such as penicillin or amoxicillin, and making her comfortable. Sometimes these hens may develop ascites or fluid build up in the abdomen from liver damage, and need to have the excess fluid drawn off with a needle.
