Answers. 1  Jeeper is correct; the US gave just over $300 Million to Greece. However, this was not through the Marshall Plan; it was through the Truman Doctrine. The confusion comes since the two were so similar and were passed together.
Breeding bald eagles typically lay one to three eggs once a year and they hatch after about 35 days of incubation. Hunting, egg sitting, eaglet feeding and brooding duties are shared by both parents. The young eagles begin flying three months after hatching and are on their own about one month later.
An Egg a Day is Work. If you think laying an egg is easy, think again! Robins lay only one egg per day for good reasons. Female birds have one working ovary, unlike mammals, which have two. Ovaries are the organs where eggs are produced. A bird's ovary looks like a tiny bunch of different-sized grapes.
