It maybe 50g.
An average hummingbird egg (literally about the size of a Jelly Belly jellybean) weighs only about .02 oz. (0.6 g.). It would take 800 of these eggs to equal 1 lb. An average chicken egg weighs about 2.31 oz. (66 g.). Six of these eggs would almost equal 1 lb. An average ostrich egg weighs about 3 lbs (1,360 g. Or 1.36 kg.), that’s a whopping 48 oz.! It would take 2 dozen chicken eggs, and about 2,400 hummingbird eggs to equal 1 ostrich egg.
