II recently got 3, 5-6wk old D'uccle pullets. They were shipped, and once they arrived one of them was very lethargic and wouldn't open her eyes. I know shipping is stressful, so I mixed some warm sugar water up and gave her about 3cc's of that and she perked up. This am she is stronger, but isn't moving around. She looks kinda like a penguin -fluffed feathers, loose wings that are hanging, and her head is sucked into her chest. I also found blood in her poop. I separated her from the other two, and bought some Sulmet in case its coccidious... What do people think may be wrong? If it is coccidosis, how long do I keep her on the antibiotic?
