Hopefully, someone with more experience will respond. I would get cardboard, blankets and hot water bottles. If you have a fireplace you can boil water and fill the bottles. Of course it you have a fire place put the babies near it. Personally, I'd use my own body heat if I had to.
Good luck.
I'm with you. I wish everyone in this storm's path safety and blessings. It is one of my nightmares, having to evacuate or try to protect all my animals from a storm.
I heard them announce that if you have a pet bring it with you. I have 7 cats, 4 dogs and 8 chickens. Now what shelter would take...
