I have a hen named June. She is a Buckeye. Recently, we've moved, causing her hatch mate to die of severe stress (back in September). June has slowly been declining in health; I'm concerned. She's weak, lethargic, slow, labored breathing. I have pictures. The last couple weeks have been the worst, she lugs out of the coop, always in this weird upright position. Every time she poops she looks like she's pushing hard. It's always black like tar and small. Her head feathers are usually ruffled and her abdomen his drawn tight. But she's SO thin. Her sternum bone is sharp and I can feel her ribs under her wing. I'm wondering, perhaps, worms? We wormed them with Wazine. They all gained weight, even June for awhile, but now she's losing weight again. I've done the homework, I know Wazine is not a great thing to worm with, but we had it on hand. She is currently eating laying pellets with oyster shell, and she drinks LOT'S of water. Their coop is movable and they get fresh grass everyday, lot's of digging and dust baths. They free range about 3-5 times a week and have almost half an acre of goodies to dig up for an afternoon. The rest are thriving, but June isn't. Any input?
