Congrats on your eggs. Make sure not to turn them over and try to keep your temps as stable as possible. I've heard temperature spikes can cause baby's to have problems with their temperaments :p
When I had a clutch i just used a simple hovabator you can buy at any feed store made for chickens. Something with a digital thermostat would be better though. I used vermiculite as a substrate and added just enough water where it would clump but not drop with water and sealed the tub.
As far as breeding those 2 together. It's something that happens but like with any species, in like breeding should be kept to a minimum.
