Tonight, I candled 17 shipped eggs. 9 were set on 2/10 and 8 were set on 2/12. The eggs set on 2/10 got lost in the mail for 7 days and may have traveled through some very cold weather. Of these 9 eggs: - 5 had blood rings - 3 were cloudy - 1 had an embryo that was visibly moving and had a well-developed network of veins The eggs set on 2/12 were placed in the incubator within 4 days of being laid. Of these 8 eggs: - 2 had blood rings - 3 had loose air sacs - 1 had a bubbly air sac - 2 were dense in the area of the egg that I'd look for the embryo Temps and humidity have been perfect. I allowed time for settling and rising to room temperature when they arrived in the mail. I've never attempted to incubate shipped eggs before. The eggs were very well packaged...of the 18 shipped to me, only one arrived broken. My hunch is that the first batch struggled from a combination of being at least 7 days old (without being turned while shipped) and cold weather (possibly freezing temps). I think the 2nd batch just got handled to roughly by the mail service (the 2nd batch included the cracked egg). Would these conditions have resulted in blood rings, though? I understand blood rings to indicate a quitter...I guess I was thinking the impact of the conditions would affect whether or not the embryo would begin to develop...not its chances after development had begun. I'd appreciate learning from your experience with shipped eggs. Thanks!
