So I moved a broodie hen and her chicks into a "nursery coop" they've been in there for about 1 week. It looks like they have warts on their faces and beaks. The chicks' beaks look swollen. I know these pics aren't the best but I'm hoping you guys could help me out. What is it and how do I treat? You can see the inflamed pink line on the chick's beak near the nostril.
