What should be done to all cold food before feeding to the bird?

Warming cold food in warm water before feeding it to the bird is essential for several reasons. Birds, particularly those in a falconry context, have specific dietary needs, and providing food at the right temperature can promote better digestion. Cold food can lead to digestive issues as it may be harder for the bird's body to process, potentially causing discomfort or health problems.

When the food is warmed, it becomes more palatable and mimics the natural temperatures of prey that birds would encounter in the wild. Additionally, it can help stimulate the bird's appetite, encouraging them to eat more readily, which is important for maintaining their health and energy levels. Thus, warming food in warm water is the most appropriate preparation method to ensure the bird is fed safely and healthily.
