Hi, all, I found this site the other day and am really enjoying it. Lots of good advice here. Question.. I am building a new incubator using and old fridge out of a camper. I was looking for ideas on an auto egg turner and came across some old fridge automatic defroster switches which I think will be perfect for the job. (.50 ea is good too ) The one I plan on using has a cycle of eight hours which means the eggs will turn every four. Is this too often? Will it affect the eggs if they are in constant motion? (alough very slow). Thanks, Dave.
