I do it different than most. I candle again if no movement seen them I do a tiny safety hole to make sure there is no movement or signs of life. If all set the same day I do it 1-2 days after others hatch. I have never had one not at least be pipped a day after others and still be alive.How much longer should i give 2? Its day 22.
The others are doing well!
But most wait till day 23-25..... mine hatch day 20 most times so I check day 21.
