Please help, my hen has bright green runny, gelatinous poop. She's lethargic, not drinking or eating. I've been reading here where this might be a fungal infection. How do I help her? A few days ago, one of my hens started coughing and sneezing, so I administered 1 tsp of ACV to their gallon of water. Her symptoms improved, but now another hen is very ill. As I watched, the sick hen appeared to have vomited some water up, though she kept her neck straight and her head level. I don't know what's going on or how to help her, so I put her in their coop and closed the door. There's a light bulb for some heat, fresh food, and water with ACV. Her straw is fresh, and the floor is dusted with DE underneath it. Thank you.
