I have 18 of the 24 on lockdown, as I am erring on the side of caution because I am new. As you may remember, I had one egg that was broken on delivery and another that seemed to be cracking and seeping around day 15. I also had one that I had identified as a clear on around day 7. Before lockdown, there were 3 more that had clearly quit developing. I have a forced air incubator and I took the tray out and laid the eggs on the mat equal distances apart. It seems this morning that some have rolled into 2 bunches, which is pretty darn exciting to see independent signs of life. Day 20 started this morning about 6 a.m., so I am on the edge of my seat. I haven't heard the first pip though!
