I have 8 Ancona duck eggs that were shipped from NC to OK. All 8 were fertile and have been developing perfectly when candled. However, one egg had no movement when candled on day 18. I checked again this evening and still see no movement in that one egg, although I can see distinct movement in all the others. The egg with no movement has also lost too much weight, while all of the 7 other eggs are right on track with weight loss. The ideal weight loss for the questionable egg was to be about 8.5 grams, but it had already lost a bit over 10 grams by day 15! (None of the other eggs has a weight loss anywhere near this level). This egg still has good veining that I can see and there is no odor, but the fact that it has by far the biggest air cell, no movement, and too much weight loss has me very concerned and suspecting it is no longer alive. If the egg has stopped on day 18, would there still be easily seen veins 24 hours later? Would you recommend doing a water float test? How can I tell if it has indeed quit? This is my first time incubating eggs and I am very hopeful for little ducklings on or around the 23rd of this month. My incubator (Incuview) has been very consistent and I am very pleased with holding accurate temp and humidity. Thank you in advance for your input and help. The 8 eggs thank you too!
