I'm in the same situation, mine should have hatched on Saturday though (although it was late saturday when I put them in, so more or less in same position as you). My inci is preset temp that can be adjusted a little if not correct & you just fill a bowl and keep it topped for humidity. So, my problem could be that it isn't giving a true temperature. I'm definitely getting a digital thermometer & humidity thing (sorry can't remember the word) for next hatch.... I did have to adjust the temp upwards a couple of days in so maybe it's just late. I'm just clutching at straws really.
I had very little movement from one egg this morning, then absolutely nothing. I put a rolled up wet jay cloth in there this morning, in desperation that it might up the humidity, thinking that is a possible problem as my house is so well insulated it is very dry.. The instructions just say to fill the container and keep it topped up. I've seen posts from others who've had success using the same inci as me.... Just my luck!
I've been so looking forward to the hatch as well, as I'm sure everyone does. I set 7 of my own eggs first off and none were fertile, they were very early season eggs and my cockerel has only just started to tread the hens.... So, I then bought myself 10 eggs from a local breeder, so they didn't go through the postal system. All her stock are very healthy and unrelated. She hatches lots each year with great success, so if mine don't hatch it can only be my hatching conditions.
I got a mix of leghorns and orpingtons.
I'm so fed up :'(
