Yes, that's correct. February 22nd would be day 21 of incubation. So lockdown would be on day 18 would be the 19th. It doesn't hurt to put them on lockdown a day early if your thinking the bantams may start to hatch early. I often take mine out of the auto turner on day 17 and I just don't increase the humidity until day 18 unless I see an early pip.I'm having a predicament. I don't know if I'm supposed to put the D'uccles in lockdown today or tomorrow.
I put them in on the afternoon of the first of February. That would mean day 7 would be on the 8th of February. Day 14 on the 15th, and day 18 on the 19th... right? Meaning they would hatch on the 22nd of February? That would be day 21, right?
