Today was my 18th day. I have put my eggs in a egg carton cut down for hatching. My temp is holding at 100.9 and humidity is 68% I have a LG still air filled all the wells and added a sponge. Have the sponge placed so I can run a straw through a vent hole to add water to wells and sponge. 3 eggs are on day 18 and 3 are on day 16. I was told that being 2 days behind wouldn't hurt. So we shall see. I am sure they may take longer to hatch then the 1st 3 that are due on sat. So far so good!
