Just FYI, they do make azithromycin for birds.
I got both invermectin AND azithromycin at Ziverdo kits out of India excellent service received both in about two weeks AND there are enough pills for about 4 people add your own D3, C, and zinc and you are ready to go, they also have HCQ!!
Cool, but expensive and out of stock most everywhere. Found one website out of ten that doesn’t say out of stock. $3/tablet
