Now that the eaglet (DG1) has hatched, what can we expect to happen over the first 14 days?
- DG1 will double its weight in one week.
- A weight gain of 1/4 to 1 pound per week is expected up to about week nine or 10.
- It will take several days for DG1 to develop any mobility, so feedings are sometimes clumsy: facing the wrong direction or landing on its back.
- DG1 cannot regulate its temperature. Born only with light natal down, the parents must brood constantly to keep it warm and dry.
- The area around the eyes is dark, giving it a bandit look.
- The ear holes are visible through the thin down (which will disappear as fuller down grows in).
- DG1 will begin to move around, first in the nest bowl, then eventually out of the nest bowl using its haunches (leg bones) and tips of the wings to scoot around.
- The white natal down begins to be replaced by thicker grey thermal down, often with little tufts of down showing in places.
- The leg and foot pads change from pink to yellow.
- The beak, leg and foot pad have the largest growth, leading to looking out of proportion to the rest of the body.
