Cardinal eggs typically take about 11 to 13 days to hatch after the female begins incubating them. The female does most of the incubation, keeping the eggs warm by sitting on them almost continuously, only leaving briefly to feed. The male supports by bringing food to the female and guarding the nest during this period
. The exact incubation time can vary slightly depending on factors such as temperature and weather conditions, with warmer weather sometimes shortening the incubation period. Once hatching begins, it usually takes a few hours for all the chicks to emerge, and they generally hatch around the same time to ensure synchronized development
. In summary, cardinal eggs hatch in approximately 11 to 13 days from the start of incubation.
