I put the eggs in the incubator late Saturday, 5/31, so I am assuming that day 1 would be Sunday, 6/1. If they are supposed to hatch on day 17 (correct?) then what would be the last day I open the bator and up the humidity - the 13th or 14th? What is the ideal humidity level and do I increase the temp? Been holding steady at 99-100. Also, when I turned the eggs this morning, I had a couple that refused to lay sideways. They kept rolling little end down. What does this mean? Is this normal?
