We've lost two Pekins in the last two days. Both the exact same way. We've found the bodies against the fence with their heads ripped off and they're nowhere to be found. I'm guessing there were two predators; one inside the fence and one waiting outside the fence. What kind of animal only eats the head of a duck? Why wouldn't it take the whole thing? Today will be spent forcing the remaining ducks into a coop and building a run. Bah. This is our first time losing birds to a predator and boy, does it suck.
