eggish poop

[chick-flo-a]

My chickens have resumed their regular laying now that spring is coming. However, my Wheaten Maren is not laying and this is coming out of her vent. Looks like an unformed egg. I feed my girls Kalmbach Organic which contains calcium and vitamin D. I also give them crushed eggshells. Does anyone know what is going on with my chicken and how to help her? She doesn't appear to have any other symptoms.
Thanks!

When was she last dewormed?

Have you ever had issues with hens expelling Lash eggs or material?

If possible, taking some samples of the poop to your vet to see if worms are present.

I'd be inclined to work on hydration, get some extra Calcium into her and consider an antibiotic. The antibiotic is not a cure, but it may help with infection. The egg material in the poop is hard to i.d. is it firm or more liquid. Does she have a continual discharge coming from the vent or is what's in the photos what she's pooping?
