I had 5 healthy adult ducks this morning, this afternoon I found my WH drake, a WH duck, and a KC duck dead in the yard. All were on their bellies with their heads turned backwards, as though napping; all were barely warm to the touch. I cannot find a bite mark or a blood drop anywhere on them. They were found within 6 feet of one another, near my beehives. One hive was very excited, enough to make me go get my bee jacket to continue the investigation. The rooster and six hens were unharmed, the other two ducks were taking shelter behind their coop, Does this scenario sound familiar to anyone? I was thinking a hawk tried to carry them off, but one of the ducks was slightly under a table. I cannot find a claw mark or any loose feathers. Could something have poisoned them? I've been doing internet searches and coming up empty. Thanks for any help!
