Thanks everyone. We let them out for a bit just before dark to eat and drink and generally do duck stuff, and then we locked them back in for the night. They've been snuggled in the straw ever since and look quite content.
It's interesting posting in various places and seeing the responses. Elsewhere, we've been gently admonished for not locking them in at night with the cold temps--here it seems folks generally think we're being over-protective. I'll be clear that we are fairly new to ducks, and we certainly appreciate everyone's experience and willingness to share. Based on all the feedback we've received (and the run/duckhouse setup we've constructed), we've been comfortable with mostly trusting their ability to get out of the weather (wind especially), and so we've opted to not lock them in and just watch them very closely as we move through these first cold spells and winter storms. Today we observed pretty consistent shivering, but they insisted on staying out in the run. So we made the call that we would feel better with them all inside during the brunt of the storm. Was it the right call? They seemed content, and when we let them out toward the end of the day, they ate and drank, and acted their normal goofy selves...and then they got cold again, so we locked them in for the night.
I'm guessing we'll be locking them in for the next three nights with temps well below zero F. We'll let them out each morning in their run where they have ample water in heated buckets and free choice feed. No snow in the forecast until next weekend. We're pretty committed to not putting water or food in the duckhouse unless something extraordinary happens. As we've done so far, we'll watch them closely and take our cues from their behaviour. We'll certainly pop back in here to ask the advice of all of you with so much more experience.
For what it's worth, here's a picture of our set-up:
And as you can see here, they have a nice protected spot under the duckhouse where they can get out of the weather:
One issue with our elevated duckhouse is the elevated door, which is pretty exposed to the wind when it comes out of that direction. The idea of a "curtain" is interesting, but I can't see our guys taking to that too readily...but who knows. We do need a better job of shielding the drifting snow beyond just the single row of straw bales (the straw bales now extend around the entire length of the run, but only one bale high). We're working on that.
Anyway, thanks for all the comments and suggestions. We'll keep you posted!
