Two are here!

Two ducklings have hatched! My brother woke up at 5:00 am and told me. :) Here's them cuddling their brother/sister There are still nine eggs that are pipped (or further) still to hatch. But here’s the weird thing, there is only one open egg shell, and all of the other ones are left to be pecked open. Could these two ducklings have come from one egg? Is that possible? The egg is slightly bigger than the others, but it doesn’t look like enough room to fit two ducklings! Weird, huh?
