Has anyone heard of this before? My vet is baffled as are his colleagues. About 6 weeks ago, Kitiara started shooting out the egg shell and then the gooey part. The shell looks like a crumpled piece of paper; the yellow and white look normal - just need a frying pan. Does anyone have an idea why? She gets a good variety in her diet (starter meal, seeds, vegies, fruits, "yard food" - anything she finds outside, anything we eat that she wants to try, no chocolate, no spicy stuff, no preservative packed pre-prepared people food). She gets outside everyday (wheather permitting; she won't go out if it is too hot or too cold or raining to hard.) She is eating, drinking, sleeping and pooping as normal as ever. My other chicken, living the same as Kit, is fine. She is 2-1/2 years old. I believe she is a RIR, maybe mixed.
