Rescue situation, newer keeper

[Bogertophis]

Would vetericyn plus spray for poultry be ok to use on his back? It says on the back that it is safe for all animal species.

If you trust the labeling & are reading correctly, it should be- but I'm not seeing the label so leave me out of this decision. If any doubt, call your vet & ask, or call the company & ask- that's what I would personally do. I really prefer to use products labeled for reptile use, since cold blooded animals are often harmed by products (medications) designed for warm-blooded creatures that metabolize things very differently.
