had a 19 mo RIR that didn't act right for week or so(could find no external parasites-she WAS thin but still eating etc) and "did" her yesterday thinking I would necropsy but was so grossed out by her heavyness(lack of flesh tho)and suspected I would find fluid. Sure enough she was engulfed in water and I was shocked at how quickly it happened. Have never seen CHF(to my knowledge) as have only lost 2 hens in several years to unknown causes. So am assuming ,from the little i have heard, that more than likely CHF.Any experience with definitive CHF appreciated
