This is my first ever hatch and I've got my first two pips! Eeeeek! I'm so excited! But my question is, the incubator instructions say to lay my thermometer on top of the eggs. Well what should I do when they start zipping and trying to push out? Will the thermometer laying on top of the eggs give them any trouble? Will it make it harder for them to hatch? Should I move it or remove it altogether? What do you veteran poultry parents think?
