quail winter help

How should I go about wintering my quail pen? Will they be ok if I just throw a tarp over them or rig up some kind of tent structure? I’m mostly worried about them getting buried under snow, but I’m in Canada so we can get -30C.

I need to know what to do with my a&M quails in winter there my pets and I love them i need to find someone or somewhere to keep them anything will help
