Sally I have this on a lot of my eggs but only the shipped eggs. They have been incubated in the same conditions as home eggs who were not affected. They also have huge air cells so I've been chalking it up to a shipped egg thing. I dry incubate and other then about 24 hours mid way through, the RH has been <20%. I'll see if I can get some pics tonight.I am po'd this stupid video isnt clear at all! What is going on! I have uploaded plenty of candles and never had this issue until recently, they are clear on my laptop and my cell, and they are max on youtube! NOTICE first egg and very last egg I candle are NORMAL day 15 White faced eggs, also note that the veining (chorio-allantoic membrane) reaches the bottom of the egg and has great veining! Then I candle all those silkie duck eggs! STUNNING if you ask me! Well it is clear video to me on my laptop and in person! and NOTE MY QUOTE ABOVE! [COLOR=0000CD]So my guess is number 8 hatches! and possibly #3,[/COLOR] there are two eggs I missed, I will do them later. The silkie duck are on day 18![]()
