my ducks won't stay inside

[Dracora]

Hello, i have an issue with my ducks. this is my first winter with them and geese. here we get down to -30°C and lower, and have been hovering at that for a fair bit. every other animal stays inside their "homes" Not my Ducks... they are Always outside. and because of that they keep Dying. no matter what I do they won't stay inside. they have warm straw in their home that's dry, and have lots of food in their Homes. but nothing works. they keep Dying from the cold one by one and it's stressing me out. I feel horrible... I just want them warm and happy but while they may be happy, they won't stay in their warm house... there's tons of room. lots of places to hide, food, water. why do they keep basically killing themselves? and what else can I do to stop it. I don't want to restrict their freedom, but I have no option at this point. but even at night I'm out there having to put them to bed.

Keep their coop locked where they can’t get out is my suggestion.

With temps that low they should be kept inside. I cannot imagine anything surviving in those temps.
Very sorry for your losses.

Are you sure it is the cold that is killing them? What is their 'home' like? Are they protected from the elements - rain, snow, wind - when they are inside?
You need to lock them in at night even if you have to make them go in. They don't need food or water during the night.
