I think the idea of Orcs laying eggs is ridiculous......no mammal (except platypus and echidna) lays eggs and I'm quite sure Tolkien knew that. (though not neccesarily the exceptions to the rule.)He surely wouldn't have primates laying eggs,that's for sure.If you ask me,we shouldn't make a fuss and just accept the idea of Orcs "multiplying in the manner of the Children of Illuvatar",wich is the most direct and satisfactory answer you could wish for.
