A squirrel nest blew out of a tree in my backyard last night. It's unusually cold, and I'm worried about the squirrels. Today I didn't see them rebuilding using the fallen pieces, and the ground is covered in several inches of snow, so they can't gather new materials to build a new nest. Will they survive without their home in this bitter cold? I feed them and love watching their antics. I put out a bunch of timothy hay. Anyone have any info or suggestions? They are (very funny and cute) gray tree squirrels.
