no - I'm not sure - actually, I've just dug out a book that shows all the eggs: it says 53, but adds that 5 of these have been lost. I'm not sure how this tallies with the 56 mentioned on the website I linked to; perhaps some more have been discovered since it was written (30 years ago). The book says 17 of the surviving eggs were for Maria and four more of hers are among the missing.
