Ugggh my new flocm this year has proved to be our most challenging yet health wise, so a few months ago I posted about a possible case of RI or RD in our flock of six as 2 birds showed watery bubbly eyes and sneezing and slight weezing, I isolated them and treated them for such and they seemed to get better so I rejoined them whith the flock...now half my birds are sick whith either the same thing or something possibly alot worse, our leghorn is the worse as she suddenly got extremely sick ~2 weeks ago whith one eye swollen shut, lethargic, weezy, extreme nasal discharge and loss of wieght/appetite, plus bad smell feom either mouth or nose(cant tell). We also have two cochins who though not nearly as bad have at least partially swollen faces and or sneezing. The leghorn also seemingly had a crop issue just before this that was cleared up. Weve had a ton of smoke from canada, alot of dust from the lack of rain, and now weve picked up rats from having so many apple trees. I have no clue what to do anymore, let me know what you think may be the cause. Thanks for the advice. Ps. We dont have any poultry/avian vets where I live, if I need them tested who should I talk too?
