18 mo RIR hen(chosen becuz shriveled cone/molting) I processed this a.m. had a softball sized water filled transparent cyst(or sac of some sort?????)in her lower gut(didn't notice until she was laid open). I am not good with organ identification but seriously doubt this was an organ! she did not have external parasites and am getting ready to routinely med for internal worms.she also hasn't been laying(I THINK) any thoughts PLEASE?
