Old hen in pain when she poops
Does she still lay eggs? She could have a large lash egg (a product of internal laying and salpingitis) blocking her vent. Can you use a disposable glove with lubricant, and feel inside with one finger for a hard object? The stimulation may cause he to poop. Hens with internal laying can walk upright, and have trouble walking, or waddle. I doubt if that little bit of pate caused her problem. You can give her a little olive oil, or a tsp. of either castor oil or some molasses to work as a laxative. Make sure that she is drinking well.
