Can you share the types you collected? Process can be different based on type of acorn (white vs red) at least down in my neck of the woods where we have few freezes -- white varieties don't require cold stratification whereas red, bur, and pin do. Guessing you already know but deer will definitely favor less bitter varities initally until they're cleaned out and then will tend to move on to less favorable tasting acorns. I'm WAY south of you and primarily have planted sawtooth, swamp chestnut white oak, and live oak acorns, but am sure others on the forum will be able to help more once you share varieties, or at least point you to past related threads (been some really good detailed ones).
