Good Morning everyone

I'm seeking to connect with chicken folks who have Silkies in the northern climes. I have always had (and have) large heritage breed poultry but I am considering adding Silkies this year. My problem is I know nothing in regards to how cold tolerant they are or how well they might integrate with a large bird flock.
Anyone on here be able to help?
I live in northern Wisconsin. We still have snow on the ground. Our winters can get really bitter often having stretches where it may get barely reach above zero for days at a time (so much for global warming). I have a radiant heated, temp controlled insulated coop with an enclosed "breezeway" to the small greenhouse for my birds to play and sunbathe in when the weather gets too much outside. This entire area has clear roofing and a passive solar heating setup so the ground never freezes in winter and supplies extra daytime heat to the coop. (the venting/airflow is set up to do the opposite in summer). We keep pathways shoveled and the birds can come and go from the greenhouse whenever they want during the day. Everyone is locked up tight at night out of necessity. We just have too many predators. My coop has even, thankfully, proven to be completely bear proof.
So, opinions/shared experienced from anyone with keeping Silkies with large birds and/or in snow country?
TIA everyone!!!
