I had a hen develop a water belly, her comb flopped over and turned blue due to weak heart. She became immobile. I did research on this site reading peoples experiences and saved her. Thank you. I prick her with a 16 gauge needle and gently get water draining remove syringe and let water naturally drain. She knows i help her, when she fills up her come turns blue, once she is drained of water she perks up starts scratching. She comes and knocks on the door I let her in for a snack and send her on her way. Just sharing, they can be saved at least temporarily.
