Go Lay an Egg!
Why does Mother Robin lay just one egg a day? Carrying more than one egg in her small body would be like an airplane trying to fly with too much weight on board. One egg is just right.

Mom lets the eggs stay cool until all of them are laid. Then she starts the babies growing. She keeps the eggs just the right temperature. She spends about 50 minutes of every hour sitting on the eggs. Her body heat keeps the eggs warm in cold weather. It shades and cools them in hot weather.

Most robins lay 3 or 4 eggs for their first nest of spring. Second and thi
rd nestings of the season may have just two eggs.
