I'm not certain how many just yet, but I do know that 3 of them have it for certain.
This is the plan: We (I will have 2 assistants - one to hold and console the hen, while the other assists me in handing things to me) will wrap the hen in a towel, so she won't be able to wiggle to much and won't hurt herself or us. We will then attempt to remove the plug.
Once removed, I will flush the wound / hole out with peroxide using a syringe and then wipe out with betadine. I will then pack the wound with a mixture of Terramycin and triple antibiotic ointment that I will have made a paste out of before the procedure begins. After that is applied, I will cover the wound with a sterile gauze pad and wrap the foot with vet wrap.
Wish us luck!
