Yes, it it is a sippy cup actually! My husband gave it to me and glued a SoCo label on!!!
I'm going to check the other eggs...
There hasn't been external seepage... I had only been checking this egg, it's in its own bator. I'm more afraid it's bacterial. Had a goose egg do the external seep thing... Ewwwww!
Usually if it's bacterial you'll smell it... no joke...
