I'm not sure if it's the left overs from an egg hatching in the turner a couple of weeks ago (which we moved to a new bator, and LG, that I really dislike) and we left the other eggs in to continue. I thought maybe an egg was bad, I took each one out to sniff them, but they all stink! (I think from being in the stinky bator......) Plus one of my babies hatched last night, but it had a piece of eggshell stuck to it's butt, right over the vent........So I broke the rules and pulled it out, and ran warm water on it's bottom to get it off. I saw a tiny, tiny bit of blood, but I think I did more good than bad. I hope I did anyway!
