Mites are really small. I am posting the photo below because the bird was INFESTED with mites. They were everywhere. And she looks fine, right? I inherited her from a neighbor and I can't say how grateful I am to have quarantined them first. Since they are your only birds, I would check them over for bugs and other issues.
Oh I didn't realize you had more birds! I always deworm new birds. I like to use Valbazen, which is a soft med. Changing shoes is a must. Same with changing clothes when going in between flocks. Good luck! Very smart to quarantine first, you won't regret it. Most of the time, the new birds have no issues at all, but better safe than sorry!
I do! I have 13 silkies, 3 RIR, 4 ducks, and 2 turkeys. I'm generally the neighborhood charity when it comes to birds they've decided they don't want anymore. I always do my best to be thorough when bringing in new birds to the property. I'd hate to lose them all because I was being slack. Thank you for your advice though, because I really need to look them over closer when I pick them up this afternoon. I had went down this morning to look at them and to see what their temperament was since I knew nothing beforehand other than they had been abandoned.

If I had to guess, I would say all four of the birds were probably from some type of assortment at Tractor Supply during the last chick days. I just know when I started looking up birds, I didn't see anything that completely matched her. So I wouldn't be surprised if she's not a bit of a mutt.
