How many eggs does an average bald eagle lay in a lifetime? The average Bald Eagle clutch size is just under 2 eggs / clutch (1.9). If we assume that a female eagle begins nesting at age 5, and lives until she is 25, she will have 20 years of egg-laying. There is no evidence that a healthy eagle reduces egg-laying as she gets older. So 2 eggs/year x 20 years = 40 eggs in her lifetime. â PN
The photos above compare two bald eagle eggs that came out of the Norfolk Botanical Garden nest in 2008 to a tennis ball and a baseball. The shape of the egg is called oval. The two eggs with the tennis ball and baseball measured 74mm X 56mm. One weighed 126 grams (4.5oz) and the other 122 grams (4.3oz).
