What is killing my ducks.  I had 21  ducks, 5 years to 1 year old.  This morning i lost my 4th duck with in 4 weeks. First one died about 4 weeks ago, the 2nd died one week after the first.  The third duck died 5 days ago and the fourth died last night.  What diseases might be attacking my flock?  The duck that died last night seem to be a little weak  kind of droopy when she walked for the past two days. She ate but separated herself from the rest of the flock.  Two nights ago I found her in the run and had to pick her up and put her in the coop.  The ducks that died are only Ancona.  I have never had any of my ducks just die like that.  What might it be.
