You're doing great! Be confident that you're doing the right things and this little gal will heal just fine.
The goal of wound care is to prevent infection while you encourage new tissue growth over the wound. By all means, continue the Epsom soaks. It encourages blood flow which will nourish new tissue growth. An alternative, if you are strapped for time one day, is to use saline wash to clean the wound each day to remove bacteria that will inevitably accumulate. You can make your own or buy it in the aisle where the bandaids are sold. Saline will wash away bacteria while preserving the PH of the tissue.
Then finish by smoothing on a generous layer of topical wound ointment to keep the wound moist so tissue will grow in more quickly. You can get some non-stick gauze pads to place over the wound and then wrap it snugly, but not too tightly, with Vetrap to keep the wound clean and to keep the flock from picking at it.
She can go back with the flock this way and heal even faster with her mates. Slowly, you will see new tissue form at the outer edges of the wound and slowly march toward the center, forming a ridge like a volcano called granulation. This is normal. When the new tissue meets at the center and finally closes, she's healed!
