How much does a newborn eat?
I've looked around and found nothing definitive. One site says it depends:
Q. How much food does an eaglet require daily?
That would depend upon the eaglet's age, weight, growth stage, level of activity, and other physiological factors; requirement thus varies or changes from day to day.

This one says:
Eaglet Growth - The young birds grow rapidly, they add one pound to their body weight every four or five days. At about two weeks, it is possible for them to hold their head up for feeding.
By three weeks they are 1 foot high and their feet and beaks are very nearly adult size.
Between four and five weeks, the birds are able to stand, at which time they can began tearing up their own food.
At six weeks, the eaglets are very nearly as large as their parents.
At eight weeks, the appetites of the young birds are at their greatest. While parents hunt almost continuous to feed them, back at the nest the eaglets are beginning to stretch their wings in response to gusts of wind and may even be lifted off their feet for short periods.

If an eaglet gains one pound in four to five days, I would think in my humble opinion the eaglet would have to eat at least that much to gain that much in that time frame (3.2ozs per day - 0.09kg). You also have to consider the waste products produced by the eaglets digestive process, that one pound could be a pound and a quarter/half in four to five days.
It's hard to tell, but this may be the Mom feeding the eaglet or helping the other one emerge from its shell:

I have noticed since the eaglet was born between yesterday evening and this morning it has become increasingly difficult for the Live Bald Eagle Nest Cam | HDOnTap.com |

If this happens just reload the page, in some of my attempts I've had to try up to four times, but I eventually got in.
