To answer both your questions with one answer, Yes. Cherry is one of my favorite woods to make calls out of. Be it pot calls, deer grunter, crow, or owl calls. It's an ideal wood, and turns easily.
The wood has to be cut and dried. Calls made out of wet wood crack and split, so once its cut down, it still has to go thru a drying process. Kiln drying is quicker, where air drying will take quite some time. But either case, it has to be done. Hope this answers your questions.
