Do Ducks Eat Chiles?

I'll let you know how this one turns out... Fed the ducks chiles. Once we were at a BBQ and the homeowner's geese were eating a ristra of red chiles. We were told that geese can't taste the heat. Hope ducks can't either. Anyway, we bought them from Oklahoma, but they are after all going to be NM ducks. Googled it and found recipes on eating ducks with chiles. Nothing about feeding ducks chiles.
