Doxy/Tylan (100 gram packs of powder. Used to combat respiratory and related diseases.

Excellent product. I knew we likely were dealing with mycoplasma from birds at auction. Then it hit my flock. I knew they had likely contracted it, as I made the mistake of not doing a quarantine on the new birds. And despite removing the sick bird from auction, it hit my flock on day 13 post exposure. I read and read up starting on day after auction when I realized I had brought back 1 sick bird. Ordered this to have on hand just in case and via priority I had it within 3 days of ordering in advance. Almost out of the blue when I started thinking I got really lucky my roo started sounding like he was breathing through a watery straw and coughing/gagging. Like pneumonia sounds. Overnight. When I say without this on hand he was probably toast, and I still was scared. I mean it. This likely saved my whole flock. Day 4 and they can actually function. He sounds 80-90% clear. Continuing our dose, I mix it in 1/2 gallon batches and that works best to keep it fresh for me. So grateful for the quick shipping a day after a holiday and this lifesaving product. I absolutely will keep on-hand, and probably add some other emergency items just in case.
