Before hatch: the Hatchwatch Clock counts UP from the time the egg is laid.
After hatch: the Hatchwatch Clock is reset to track the age of the offspring.
- Bald eagle embryo take 35 days to develop when incubated at 99 degrees.
- The range for hatching is 34-41 days; only rarely would an egg hatch outside of this range.
- Begin to watch for a ‘pip’ in the egg as day 35 approaches.
- First eggs may take a bit longer to hatch than later eggs as they sometimes are not intensely incubated until the arrival of the second egg, the brood patch may also be less well developed, and the initial incubation temperature may be slightly lower.
