I have about 60 ducks. I love ducks and never had a problem raising them. BUT on Thursday, I found a dead duck (one of my Favorites). I had seen her an hour sooner and she seemed fine. I haven't seen anyone acting sick or ill except one other little lady has bumble foot; which I just treated with ducky surgery today. Anyhow, I saw her about 1pm, and about 2 I went to change their water, and she was dead. I was immediately saddened and started to cry as I picked her up and I was about to hold her and hug her lifeless little body, and realized she smelled like she had been dead for a week. I flipped her upside down and she had A HAND FULL of maggots fall from her vent; which by the way was very loose. Today, I went out to my truck to see if I left my phone charger in it, and saw another favorite of mine (Flop) dead out by me tractor. I had had her longer than any of the others but that's only like 14 months. It was suspicious since SHE hadn't been sick either (as far as I knew) and sure enough... she had (not as many and not as big) maggots in and on her vent too. She had to have only been dead for about an hour too, since she wasn't there when I fed the cows an hour earlier. I don't understand what happened. HOW did this happen? WHAT causes this? HOW can I fix it. This is devastating. I have 15 Drakes and 45 girls; well, I did! I don't want anyone to suffer, I don't want anyone to die, and I need to know know how to fix this.
