With humans the wound is cleaned and stitched and the person told to keep dry no water for 5 to 7 days depending on wound size. And of course don't lick the wound (teeheehee).We do what works, what we can, and we all learn by trial and error with the help of everyone here. I’ve seen wounds I definitely wanted to suture, (my friends mink attack victim comes to mind) and some that probably should have been but weren’t and managed to heal up just fine… a rescue hat I took in half healed who was being cannibalized by her tribe (Zeta) and a few deep spur/mating injuries on hens. If I had more confidence in my stitching I might try it, I was literally thinking two or three little stitches could pull this together just fine… but the skin is so delicate… heck even on mature chickens their skin is super delicate.
My friends mink victim managed to heal up, despite the absolute worst bandaging job I have ever seen. In fact, the tear was made far worse by the first bandaging attempt by him and someone else. If he had let DH and I do it, it would have gone so much better. The wound of course got infected (filthy coop conditions) and she still survived, but as you said… with massive scarring and a now permanent bare breast where the skin had to regrow over the gaping hole (because he wouldn’t let me close the edges anywhere near each other, like a 4” patch of no skin at all)
I think with most people being stitched up the level of sterilization is much higher than we can get at home, and it’s often not super tightly closed… that’s one of the main issues people have when applying steri strips and butterfly closures on wounds themselves (they are really hard to get here now)… infections and abscesses still happen more often than you would think, DH’s worst scar was from a botched stitching job after a pacemaker replacement which resulted in a major infection, removal of the pacemaker and it’s now on his right collarbone. He’s had several open heart surgeries, and is now on pacemaker #9…
Hard to get any animal to not pick at, lick, roll in dirt, get wet their stitched wounds. Or any wound for that matter.... The living body is an amazing thing tho, and has these amazing infection fighting abilities, but of course the very young and very old are at more risk of mortality of infection complications such as sepsis.
Another complication of wounds is loss of body fluid, big wounds not only lose blood but they leak serus fluids. So getting a wounds lips together will reduce the surface area that leaks fluids.
Adhesions happen and sometimes not much one can do, my arm fracture needed surgery and then I removed the plates and screws so the wound developed adhesions, most I was able to massage out but one still remains. I am betting you are not likely to massage the wound on a chicken!! The risk is adhesions reducing leg or wing mobility.
Anyways the long and short is living organisms are amazing, and sometime despite ourselves they manage to heal
