Cooling alone seems to increase hatchability by 1 chick in every 65 chicks you hatch.
Honestly, I don't think that's enough to start a whole new technique when some of us need to concentrate so much more on temp stability and such.
Lets get the basics right before we start tweaking.
Agreed, if new hatchers dont have the basics of their bator down pat there is no reason to do anything other then get the bator stable to begin with.
However on the same note, if people are going to be incubating goose and duck eggs they need to be aware they are nothing like dropping some chicken eggs in a turner, waiting for lock down and upping the humidity. Goose eggs need hands on attention daily from day 7 till lock down. The person incubating them should be wearing gloves or washing their hands very well before handling the eggs. (washing for 5 seconds doesnt count, a minimum of 30 seconds before handling the eggs). They also take much longer to hatch, and will cause panick in first time goose hatchers making themfeel the need to "help" when in fact the gosling is progressing properly. They go very inactive and rest for prolonged periods of time before showing true signs of progress at hatching. Its enough to drive a seasoned hatcher crazy for sure.
