We are processing a few culls and then our cornish X. how do you rest them and how long does it take? most of ours before were just boiled whole and used in casserole or something similar. we are planning to process about 15 at once now and need to know how long to wait before freezing them, and where to keep them to "rest". in the refrigerator, cooler on ice, on the counter covered? what is the quickest way since our fridge has limited space.
