1 After about two weeks, they start to look more like small adult hummingbirds. 2  By then, they have grown real feathers and their beaks (depending on the species) are often longer. 3  After three weeks, the young birds are ready to leave the nest forever.his is a relatively long time for a bird incubation. When the baby hummingbird is still in its egg, they have strong neck muscles and a hook on their short bill in order to peck their way out. Hummingbird babies are born blind and naked without feathers.
Incubation begins as soon as the eggs are laid. There are a few erroneous reports of an incubation period of only 9 - 12 days. Since the incubating female must leave frequently to forage for her own food, as well as additional nesting materials, incubation takes longer than expected for such tiny eggs.Realistically, it takes about 14 - 17 days and sometimes up to 23 days of incubation before they hatch.If the weather turns nasty, it extends the incubation period. Once the eggs hatch, the almost impossibly small hummingbird babies emerge naked, totally helpless.ince the incubating female must leave frequently to forage for her own food, as well as additional nesting materials, incubation takes longer than expected for such tiny eggs.
