How is her crop feeling this morning? You can try checking again for a stuck egg inside her vent up to 2 inches. Soft or shell-less eggs can be hard to pass. Lash eggs from salpingitis can be stuck farther up. Collect some fresh droppings before you go to the vet. Is she showing any signs of molting with feather loss or looking a bit ratty? What were you using for coccidiosis? I would get some Valbazen or SafeGuard Liquid Goat Wormer to worm her later today. Valbazen dosage is 1/2 ml orally and repeat in 10 days. SafeGuard dosage is 1/4 ml per pound—1.25 ml for a 5 pound hen. Give it once and repeat in 10 days, or if you can, give it for 5 consecutive days to treat dangerous worms such as capillary worms.
