Timothy,
What a good question. You are right of course, that montremes as animals 
are closer to birds than reptiles, being warm-blooded. However, the eggs 
of monotremes are soft and leathery, like those of reptiles - no-one 
really knows why. You may find the information on this pages useful.

Thanks for using MadSci Network.
