It's day 18, and I am just about to take out my automatic turner and put the eggs on their sides for hatching. What do I do with the thermometer, put it on the eggs and have them hatch underneath it? Then the chicks would knock it about? My still air hova-bator doesn't hold its temperature well and i feel that I need to have the thermometer in there somewhere. What do others do in a full incubator!?
