OK First off let me be clear I have only hatched 3x and know just enough to make me DANGEROUS ! However since I don't see any other replies I will try to help ya.Good Morning Folks,
Today is hatch day. I am wondering how long you let your incubator run before you decide that an egg is not going to hatch? I thought I'd ask you folks, before I go sorting through threads.
Did you candle and did this egg look good when you candled ?
If it looked good on candling I would wait until all other eggs have hatched then give it about a day probably no more. See the sounds of other chicks may encourage it. If after most of a day I had not seen or heard any signs I would carefully candle and make a final decision.
Keep in mind I am not one of the "PRO's" (and I don't mean that disrespectfully). I just get a lot of info from those who REALLY know! I may be all wrong and they will probably correct me which is good.
Good luck.
