A robin lays one egg per day and stops when the eggs feel like the "right amount" to be sitting on (usually four). Until she's laid a full clutch, she usually allows the eggs to stay cool so the babies don't start to develop. That's smart! It means all the babies hatch close to the same time, 12 to 14 days after she starts incubating. Even in good weather, she rarely leaves her eggs for more than 5 to 10 minutes at a time.
