So today I was going to mist my duck egg and I saw something odd on the shell so I took it off using a paper towel but as I did that, it took a little piece of shell too. It didn't go all the way through, there is still a film like thing underneath but should I take action and if so, how?
So today, I candled my one of my 10 day old eggs. It didn't look fertile so I cracked it open. When I cracked it, I saw the little white spot that showed it was fertile. Could my egg have hatched?
