I am on the 22nd day of incubation for my eggs. The development seems complete when i candeled them a few days ago after i took them off turning. as far as air cell, and things are concerned but i have yet to see any signs of life in any way, no peeping no pipping no movement. at what point should i give it up and throw them out, and what could have went wrong. the same thing happened with my last batch i left them in 26 days and finally threw them out. What is going on here. (by the way the temp. was a constant 100, and the thermometer was not wrong because i thought it could be so i put another in and it also said 100. ) any assistance would be helpful because im getting really frustrated here, i payed a lot for the eggs.
