I built Miss Prissy's bator and had 10 duck eggs in it for my first hatching experience. I hadn't seen movement for some time. Some of the eggs started to turn black and smelled terrible. I decided throw them out and start over because I read that they can explode. I opened one end to see if i could see how far they got before dying. One was disgusting black ooze. Then next one had a baby in it still alive. the hole is too big to use wax and there's a tiny hole in the membrane. I've been keeping it moist and have the hole covered with part of a sandwhich bag taped over it. It is still moving after 8 hours. Today is day 23. Please tell me the best way to keep this moist and how often i should moisten the membrane. I don't want to drown it. Please don't tell me to throw it away. My 4 kids would freak out! Any advice at all would be appreciated. I have certainly learned my lesson and will wait the full 28 days next time!
