Hi All, I got six different breeds of baby ducklings from Metzer Farms a year ago. They have a wonderful life here in Southern California with free ranging, a duck pond, corn in the morning, watermelon in the afternoon, mealworms at night along with duck food, of course. They are protected from predators in a duck run at night and have a shed to sleep in with shavings and hay. They are all doing well, but Gracie, my Golden 300 Hybrid, died in the night. I found her on her side in the coop in the morning. It was a surprise to me as she was just over a year old. Can anyone tell me what she might have died of? She had no exterior wounds on her at all. I have raised chickens before and know that they can die of anything from tumors to ovarian cancer to Egg Yolk Peritonitis, and I know ducks can get that too, but she showed no symptoms of being ill before she died. Thanks in advance for any insight you can provide. She was a very sweet duck and is missed.
