It's been a long time since I've skied that part of the country, but isn't Welsh facing a bad direction compared to Buck, Afton, and Hyland? What I recall is that Chicken was almost always solid ice from the freeze, thaw, refreeze cycles though usually under an inch of two of grooming where possible. Anyway, there are geographic challenges when trying to keep a place open in borderline temps..
Most of the runs they open first are north facing. No real issue there. For some reason the metro ski areas to the south just don't get open and get snow built up as quickly as those to the NW (troll, wild) do. You wouldn't think being 30-40 miles more north would make that big of a difference. I've seen Wild claim it's due to the valley they are in , but welch is in a pretty deep valley, as it Afton.\
Wild faces pretty much directly east. Afton Faces North and east but they open all the north facing runs much earlier. Buck faces East and Trollhaugen faces north as well.
