HatchWatch Clock 2019

Egg 1 On February 12, 2019 the first egg was laid at 6:43pm. Not viable. Approximately 20% of eggs do not hatch. Most eggs that do not hatch are fertilized however embryo failure typically occurs in one of two critical periods: either early in embryo development or late in development as hatch approaches.

The Hatchwatch Clock counts UP from the time the egg is laid.

  • Bald eagle eggs take 35 days to hatch on average.
  • As we get closer to day 35, begin to watch for a ‘pip’ in the egg.
  • 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.
  • The range for hatching is 34-41 days; only rarely would an egg hatch outside of this range.
