what substrate do you place ball python eggs on while in incubation?
You should lay them on their sides and make a pit with your finger to gently place the egg in so it doesn't move around. The more eggs the more pits but you do not need to cover the entire egg with dirt. The soil should be kept moist and heated but not muddy. Are you creating an entire incubator with a submersable water heater and all? Thats a good temp...I'm not sure how chicken incubators are made but with lizard eggs they need to be kept humid all the time so they don't dry out. I've used a styrofoam cooler with a small critter carrier in it on a stand with a submersable water heater in water that came up to the top of the stand. I setup the dirt and eggs in the critter carrier and put the cooler lid on to keep the moisture in. The water inside keeps the incubator nice and humid and I would mist the dirt once day. It's so cool when you can candle them...you're in for some fun surprises! Good luck!
Allie is right. Freeze the eggs and then toss them. The mommy and daddy need to live in separate enclosures. Since she is getting rid of them, hopefully the new owners will know better.
