Thanks in advance for your advice! I found my hen's back end covered in droppings and under that a pustule filled with maggots. I washed them and the area out thoroughly but the open/affected tissue is the size of a large egg, a little blood and slime. What can I do to keeep it clean and get rid of any other maggots and their kids?! She is isolated in the bathroom. Has any one used BluKote??
