Thanks for sharing the article! Interesting reading. What kind of hatch rate are you getting from the eggs with damaged cells?
I only get about 40- 50% of them to hatch. Before I was lucky to get 1. I have had some detached aircells reattach but the ones that are really bad end up with funky aircells once they start getting turned. From what I have read all the major organs are developed by day 5. It seems those 2 extra days make the chick stronger and even with the cramped quarters some of them do hatch.
