Hello! I recently acquired chickens, all of different breeds but from the same person. After having them for about 4 weeks, they all presented with respiratory signs. I had them tested and they are mycoplasma positive. I do not have any intentions of culling them (unless they are suffering of course). I was hoping for any tips/tricks to keep them from having flare ups. We have been using Tylosin (discontinued now) but a few have lingering sneezing, nasal discharge and 2 with rales. I have added in Rooster Booster Poultry Booster to their feed, VetRx under their wings, Rooster Booster electolytes to their water, and some herbs (Thyme, Oregano, Tumeric) in their feed as well. Any and all advice will be super appreciated and helpful. Thanks so much!
