I can't get my usual supply of oyster shells either. I've switched to scratch and peck brand, which I get at a feed store.
Also, my ducks start seeking shade around 70 and panting soon after. Yet they happily swim in ice water at 40 degrees. They just have different temperature experiences than us.
