SO great to have questions answered in simple people speak! We run a heat lamp out there, and have a heated water bucket... the ducks cant get into the chicken pen itself, we keep a 1 foot tall peice of wood between the pens that the chickens hop over but the ducks cant. I will draw a diagram sometime. ANYWAYS, from what you've said it looks like, as long as we keep the ducks from mucking it up, and have a heat lamp at the ready, they shouldbe ok with what we have.
