I posted about this huge egg one of my ducks laid this week, A 170gram egg. i decided to give my dog a treat. I cracked it into the fry pan. Out comes a yolk and egg white then clunk a whole duck egg in shell lands in the fry pan.I cracked it and it contained the normal yolk and egg. So this duck produced an egg I guess then another and both were encased in one huge shell. Awesome. I saw one on the net before but wow. Any body else have one of those.
