Hi all, First, I am an American who lives in Cambodia. My wife has a small farm about 30 km outside town. Until fairly recently, within the past 30 days I would say, we had ducks, chickens, cows, dogs, cats, and grew rice. Since then, the chickens died - well, most of them anyway. I have been trying to determine what could have killed all but two chicks. If it were bird flue that killed the chickens, I figured it would have transferred to the ducks, killing them as well. Wouldn't that hold true? Well, it didn't. I also figured it would have killed all of the chickens. It didn't do that either. Two of the chicks lived, while all the rest of the flock died. Here are the before photos of the chickens: All chickens in the next six (6) images have died, with the exception of two (2) chicks. Ducks on the farm: These ducks (white in color) we still have. All are fine. The ducks in the images below, have since been sold. All are still fine with their new owner. =========================================================================== Here are the after images (The chicks we have left): Does anyone have an idea as to what may have killed the chickens on our farm? The only thing I know, is what the family told me. We were not present at the time. That is, the chickens came in contact with a neighbor's chickens and got sick shortly after. The neighbor's chickens died as well. The family let them free range from property to property. That is a common thing here in Cambodia. For the record, when I replace the chicks / chickens, I will NOT let my birds free range.
