Dang, I hate when that happens! Sock the vitamins to it, maybe you can save it. I started adding minerals to my flock's diet to try and prevent that. I have silver laced Wyandottes, Speckled Sussex and Buff Orps hatching. Yay, I almost forgot how much fun it is to find them out there in theorning! I have my bators up on stands now, so hopefully no more snakes will get in there to snack on chicks and eggs
