I placed 6 eggs in homemade incubator early Saturday evening. I had a thermostat go out on me which caused the temp to spike and then drop. Now I'm using 40 watt infrared buld on dimmer. I candled the eggs yesterday since I was afraid of the rapid temp flucating might of impacted development. Much to my surprise I have 5 viable eggs out of 6. All viable eggs have strong noticeable veins and tiny heart beats. I'm a newbie and figured I would post here under ducks since thats what I'll be hatching(hopefully). Any advice or pointers will be greatly appreciated.
