Robin eggs typically take about 12 to 14 days to hatch after incubation begins, which usually starts after the last egg is laid. The female robin is solely responsible for incubating the eggs during this period
. Incubation involves the female spending much of the day sitting on the eggs to keep them warm, often about 50 minutes of every hour
. The exact hatch time can vary slightly depending on factors like incubation temperature; higher temperatures can shorten the incubation period by about 1.7 days, but natural temperature fluctuations caused by the female leaving the nest may benefit chick survival and size
. In summary:
- Incubation period: 12 to 14 days
- Female robin incubates eggs alone
- Incubation starts after the last egg is laid
- Hatchlings are helpless and mostly naked at birth
Thus, from laying to hatching, expect roughly two weeks for robin eggs to hatch.
