Folks I have cleaned this up for some very unkind and judgemental posts. Lets get back on track.
Ewesheep there is nothing wrong with what you did, break out analysis it's called is done all the time to test fertility and hatching conditions. Yes it's sad but some things have to be learned.
I agree that full incubation would be a better test, you need to know if they are viable right to hatch.
Bullseyes are simply not a reliable check of hatchability. With a very experienced eye they may indicate early fertility but they never indicate hatchability. They do not even indicate that they egg will start to develop. If your using bulleyes alone to check fertility you should be indicating that in your sales.
