Robin eggs typically take about 12 to 14 days to hatch after the female begins incubating them
. The incubation period starts once the last egg is laid, and the female usually does all the incubating, spending about 50 minutes of every hour on the nest
. Natural incubation involves some temperature fluctuations as the female leaves the nest occasionally, which may contribute to a longer incubation period but results in larger and healthier hatchlings compared to constant artificial incubation
. After hatching, the young robins stay in the nest for about 13 days before fledging
. In summary:
- Incubation period: 12–14 days
- Female does most or all incubation
- Hatchlings remain in nest about 13 days before fledging
This timeline is consistent across American robins and is supported by multiple sources
