Tonight I tossed 20 eggs out of 36 on day 7. They had either blood rings, were scrambled or clear. I don't even bother to crack them anymore. It does make every egg and every chick more precious...and expensive....that's for sure.
Some of the eggs came from someone I have purchased eggs from before and only tossed 2 out of 18...so you never know. I'm resigned to shipped eggs to be able to get the kind of quality birds I'm looking for...even if I only get 30-40% of them past day 7.
For hatching percentages, I use the number that I set on day 18 minus the ones that don't hatch by day 24.
