baby geese

I watched 3 baby geese take their first steps out of the nest this morning, and then watched as they - with mom and dad on either end - took their first swim around the lake, then stretched out to sun themselves and dry off in our yard. How is it they get out of the egg, and immediately know how to swim & walk?? One small (or big?) way that I'm reminded today of how God works in the details of life!
