I would wait at least 3 more days. If you had low temps you could be having a late hatch. If you want you can candle the eggs and if there is movement and what the air cell looks like. See if you can tell if the chicks have pipped any of the air cells.
Thank you so much! That is longer than I had thought. I will try to candle them tonight and will let you know. This is my first attempt at hatching thanks to this forum and everyone's kind help and vast knowledge! I couldn't have done this without it!!! Thanks again!!!
