We are on Day 9 as of tonight. I recandled all questionable eggs tonight and won't do it again till a day or so before IBW. Neither Marans egg developed, one Wheaten/Blue Wheaten Ameraucana egg had a blood ring, the last good shipped BR was clear and had a meat spot, which is why nothing happened with that one, and one BBS Ameraucana egg had a blood ring--it had a mildly cracked shell which we coated with melted parrafin wax and did at least start. I did not recandle my own 7 remaining BRs from my flock since they were fine a couple days ago and no reason to think they'd have any issues, not being shipped.
So, there were two blood rings, but none of the others ever developed and/or had blown aircells.
Remaining eggs going into Day 9 are:
7 BRs
5 BBS Plymouth Rocks
6 BBS Ameraucanas
1 Wheaten/Blue Wheaten Ameraucana
Total 19 left
The incubator is doing very well and no temp or humidity issues at all. Humming along beautifully. The P.O. did a number on these, but those tough Ameraucana eggs, boy.
