very cute coop i love the signs lol .
and your ducks look so happy there .



you want to shield them from wind with some kind of tarp or heavy duty plastic sheeting on two sides of the fencing you have for that run you donāt have to make it go all the way up to the top though. when itās freezing during the day they donāt need the pools just the drinking buckets. if you can , get a heated water bucket. i run an extension cord out and use a heated bucket, with 15 ducks I need more than one bucket so until I get another heated one I just come out several times a day with boiling water to pour on top the other buckets to keep them from freezing.
the coop for overnight still needs the ventilation, donāt be tempted to cover any windows . they need the windows up high. my coop has high windows and also low windows with 2 layers of hardware cloth - because my coop gets very hot in the summer. i only cover the low windows for the winter .
add extra straw in the coop for warmth and never use a water bucket inside the coop overnight. moisture can cause frostbite. and s backache for you because they will always make huge mess with any water in coop overnight. My ducks have gone without overnight water since 2015..
also toss some straw around in the ground in their run if itās below 25 degrees my ducks get cold feet . you can tell because they will lay down and tuck their feet in for warming
