I am new to incubating eggs. They where all candle at day 18 and were all looking good. Most of the eggs have been shing for a couple of days and some have stopped. Havnt herd any chirping. No piping. We are on day 23. I thought maybe because i didnt get the incubater up to temp before i put the eggs in It would take an extra day. Not sure but am worried something is wrong as some havent move for a day and no piping. Does this sound normal.
