I admit I am not concerned about using meds that are expired. I think in most cases, the worst scenario is they aren't effective.
Yeah, I wasn't clear, I know you have nothing to sew together, and was really talking about future reference on the suturing. Running my mouth.
Traditionally, "dirty" wounds are cleaned with dilute Betadine or the like, but truth is, I'm not big on this, either, unless we are talking about visible dirt, like a road burn. I either would have squirted it with saline or simply used the Neosporin. What I have found on myself is that Neosporin relieves discomfort, so I reach for it automatically. (I keep saying Neosporin, but I buy the generic, which is probably triple antibiotic.)
I wouldn't use E-oil til the scar tissue closed over, or nearly so; then it might improve the quality of the scar tissue. It's not something I've experimented with much, though. And I know nothing about spray-on bandages, though, again, it is closing stuff in, I assume. You could have a problem with maggots if the bird is not indoors, or even if it is, for that matter. I might try it in that case, although I'd probably try a nonstick dressing first.
