Apparently, size matters:

An average sized ostrich egg weighs about 1.5kg, and takes 40 minutes to cook.

Weighing in at nearly 2kg, an ostrich egg is roughly equivalent to twenty-four large hens eggs and can take up to two hours to hard boil.

One ostrich egg equals 20 to 24 large chicken eggs. The eggs make large batches of scrambled eggs or omelets. Soft-boiling one egg requires approximately one hour while hard-boiling the egg takes one and a half hours.
