The answer is, don't do that. I know, but it's done. So I built a bater. I put in some leghorn eggs to test with and everything is going well. The whole reason for the eggs was to test the bater and watch it perform because I was anxiously waiting some malay eggs. So I got the Malay eggs in and loaded them in the turner and realized that I didn't want to get rid of the 10 day old eggs. So now I have one set of eggs at 13 days and one set at 3 days. When I approach 18 days, I need to move humidity up (so I read) and stop the turner. I can stop the turner but do I need to build a hatcher. Someone told me that hatch quail eggs all the time like this. They stop turning the ones that will hatch and turn the ones that won't. I could set the turner up to turn 2 rows and leave 2 alone without increasing the humidity. Would that work. Is the increase in humidity the last 3 days important??? All this because I couldn't throw out the eggs. Silly probably.
