Recently went away for 9 days. Normal housesitter. Right before this we took our Sweetgrass flock from 13 down to 4. Came home and noticed one girl wouldn't put weight on her leg and another had fowl pox already crusting over. Third hen and tom were fine. Put the injured hen into quarantine with vitamins in water and brewer's yeast in food. The healthy hen now has signs of fowl pox and is pecking a hole in her own foot. I'm not sure what to do with her foot besides Blue Kote (I know it's not ideal), if they need anything else for pox, or what else to do for the hen's leg. I checked for bumble, extended both legs, and checked for pelvic issues. Her foot seems a bit tender to touch, but no signs of issues. Help?
