I will! I am almost wondering if the pullet's symptoms match Coccidosis. They are all 14-15 weeks old and I would think they would have developed an immunity by now but it is possible she was just genetically weaker. The symptoms seem to match her, lethargic, puffed up appearance. We have had a couple periods of massive rain (2+ inches in a day) that could have caused the bacteria to thrive. The other babies seem healthy, but maybe I should treat them all.
Do you have an idea if their poop is bloody or mucousy?
If you treat one I would treat them all!!!
