Hmm, have you felt between her legs for swelling? There's naturally going to be a low hanging area but you're looking for swollen tightness. Have you checked her crop?

Thank you for the advice . You may have been right with the swelling after comparing and contrasting my chickens. I suspect It’s Salpingitis based on lash eggs found in the coop about a year ago. I appreciate your help.
