Plucking is what most vets do I think.
Based on my experience with wounds, that wound is not the type they would suture closed, especially as old as it is. My vets say that these heal best when left open.
Great pitcure! That shows how a wound should be cleaned! :bow to your vet
Could be teeth. Let me see if I can find one of mine so you can compare.
Question, other than cleaning, what else did they do?
Here is one that I had:
It might be okay if the nutri drench doesn't contain any calcium. I would Google tetracycline drug interactions and double check the nutri drench for those ingredients. Generally speaking, I don't use more than one drug at a time in the waterers.
If you are worried about whether or not they are eating and drinking enough, start weighing them in the morning. If they are eating and drinking enough they will not be losing weight. I
Did your vet weigh them?
Trust your gut! If you feel like the vet did not assess the wounds properly, then very carefully take a close look at them and clean them if they look like they need to be cleaned.
Normally I would clean and debride, but if your vet thinks it's better not to, then I would listen to him/her. I don't want to contradict what your vet suggested because it could make matters worse.
I am very sad for you. :hugs My best advice is to follow your vets instructions and if any start looking more depressed get them back to the vet ASAP. In the meantime, keep them in a warm, clean place.
