We run 3 incubators with intervals of seven days between each. Eggs are hand turned so they hold more.. We have been having a 70% hatch rate with average of 50 eggs per Bator. Some are full breed and some are crosses. Lately some of the crosses are so Darn beautiful. Smokey Grey's and various splashes of uncommon blends. Hard to keep in mind that you can't keep them all sometimes. I have to post a pic of the smokey gray baby. I love the cross combinations!
