Go get some Corid in the cattle section of your feed store and start all of your pullets on it in case of coccidiosis. She has that puffed up or hunched look that is common in young chickens. Other symptoms are diarrhea possibly with blood, not eating, and sleepiness. Corid dosage is 2 tsp of the liquid, or 1.5 tsp of the powder, per gallon of water given for 5 days. Afterward some poultry vitamins and a bit of plain yogurt or probiotics will help get them back on track.
