Kiwi's Adventure

Kea congratulates you:

Well done! Let’s say there is a bird’s nest with a mother and one egg. As the egg is hatching, at some point the chick will only be halfway out which means the mother’s 2 wings plus the child’s 1 wing equals 3. When the child hatches, it is 2 each for 4 total. When the child leaves the nest and only the mother is left, it is 2 wings.
