I was the same way...hatch one was 20% opening a lot to candle ...hatch two was 77% opening every 3 days to candle and hatch 3 was 98%! Hatch 3 I put the eggs in the bator and didn't touch them but on day 7 to candle and day 18 to candle and lay down! I am not saying that it makes a big difference but I, PERSONALLY, will stick with the last method from here on out! It was hard, but I just made myself put it outta my head!
Either way it is so neat to have eggs and knowing that you helped them hatch! I wish you tons of luck on your hatch!!!
Well I candled tonight on day 7 and it looks like 15/25 have awesome little spiderwebs of veins going everywhere. My only disappointment is that a beautiful turquoise blue Americana eggs looks to be infertile.
