Update: looks like the week I spent soaking it in Epsom Salts, then changing the bandage every day, worked.
No issues how that she's been out for about a week.
Just looking for feedback.
Got a hen who I found with a large scab on the top her foot last week.
Read around and decided to go with the following treatment:
1. Isolate her in the coop
2. Daily soaks in Epsom Salts, massaging until the scab comes off
3. Apply Iodine & Change bandage...
