Hi! Just to update, this morning, I opened up the coop to find FOUR other chickens who were sneezing and lethargic, for a total of 4 Buff Orpingtons (out of the 5 BOs we have) and one Red Star. So far, the rest of the flock (we have 51 total) seem unaffected. I called my vet, and he came out. He feels they have an air sac issue (I cannot remember the name of it) but recommended quarantining them which I have done. He gave me a special medication to put in their water (for all the chickens) and I am just to watch them and check back with him in a couple days. He said to anticipate losing some of them. Honestly, I was almost expecting that first Buff to be gone by this morning, but tonight, they were all alive, and they have been eating and drinking a bit, so I am hoping that the medication will work its magic. We have been working on getting rid of worms found in the flock's fecal specimen, and the vet feels that the chicken's immune system was weakened by that, allowing the infection to come in! Geez! Anyway, I am just doing the best I can and hoping for a good result, but am prepared for the worst!
