@Kris5902 I thought of a few other items that might be easier to get.
A silver sulfadiazine gel. Usually sold in the first-aid aisle of the pharmacy. I use this myself. I prefer this to triple antibiotic ointment. I've had an abscess myself and I drained what I could, filled the wound with the gel and covered it for 3 days. When I took the dressing off the entire wound was almost healed!
Manuka Honey is another one I thought of. My friend had a young stallion barrel horse who punctured his leg right next to the tendon sheath. The vet didn't want to suture it so she recommended filling the wound with Manuka honey, placing a dressing over it, and changing it every other day. The horse never had an ounce of infection, no proud flesh, and is sound as ever. He's currently running 1D barrels and winning money.
Cannabis ointment. I know it's legal in Canada and in my state it has medical approval so I researched it and it is naturally anti-microbial and has excellent pain relief. Also topical use does not create a "head high" so he wouldn't be unable to do his rooster duties.
