I have a flock of 18 ducks, now down to 12 in just one day... We had 6 ducks suddenly die with no symptoms. (We just got those 6 ducks that died about a month ago) So thinking they must have been carrying some sort of disease... and now im afraid our whole flock has it including our 10 chickens as well.. All seem well. But if they are just going to keep dying we may have to cull them... Before we do that im just looking to see if anyone has any information that could help with something like this first.
