With as full as you said the eggs are, and if temps have stayed steady 99.5-100, then you may see pips day 19-20. Actual hatching should be within 24 hours after pip. good luck!
Congrats on your hatch. Do you already have the brooder ready for them? I hope it is a large one with 28 chick you will need a big one. One of my hatches I had 20 chicks in a 1 1/2 x 3 feet and they outgrew it fast. Had to put them outside with a heat lamp early this spring.
