Are there any specific signs/ways to confirm a double yoked egg-other than cracking it open? Can ducks have double yokers? The past few times I've candled this egg in particular, I thought it could definitely be one. Now tonight I'm really starting to think it's possible. There are 2 different dancing shadows in there, relatively close to each other but they both have the black "eye" & are not moving in sync at all.Thanks for any comments, advice, or opinions! (=
