I can’t go away for two weeks or so because I want to keep a bead on these babes every day.
Yesterday I saw both parents at the nest feeding their babes at the same time. A robin might make 100 feeding visits to its nest each day— There's no time to go far on a food hunt. Newly-hatched robins weigh 5.5 grams—a little less than a quarter.
The first baby hatches 12-14 days after the last egg is laid. Eggs usually hatch a day apart, in the order they were laid.
For the first four days of a nestling's life, the parent birds regurgitate partly digested food into each baby's mouth. By five days of age, the nestlings get earthworms that parents break into small mouthfuls. The babies eat more each day. Soon parents give them whole worms and large insects. Each young robin may eat 14 feet (4.27 m.) of earthworms in a two-week nest life—and worms are not even their main food!
Baby robins reach the size of their parents after just two weeks.
