All 21 eggs we have incubating are going strong .... except this little guy! The photos below are from a few angles - (Please ignore the air cell marking lines - we are hatching in three separate classrooms, and my coworker marked all the air cells incorrectly, I never observed an air cell in this egg) The air cell has not been clear since I began candeling at day 7. Today is day 11 and we are approaching day 14 - when i have read you should generally take out any non developing eggs. Is this a blood ring? I have seen them before but always going horizontally instead of vertically. Should I give up on this guy? Anyone who wants to follow along on my journey of teaching early agriculture and life sciences while meeting rigorous science standards in my head start classroom- please check our our website!
