2 of the ducks looked like they were asleep with their heads tucked into their wings. No visible injuries. The third had her entrails coming out her backend. 2 are missing with a few organs lying around but no bodies or feathers. I am completely perplexed. Could the 2 have died of fright? I am in California and have a few small tears in the chicken wire from squirrel damage. Please help if you have ideas.
