I candled the six that I received for replacement- they are on Day 16. Four of them have a chick moving in there, one is questionable. All have a great air cell except one of them. 3/4 of the egg is an aircell. IT is HUGE. The only egg in the entire incubator with an aircell like that. How can only one egg not have enough humidity but the rest do? THere was a moving chick in it, though. One I think is no good at all, liquidy and I should toss- but Im scared to, in case I am wrong. Doesnt sound too bad- except that these four plus the two others (one that hatched early and the one I hatched) are out of a total of 28 eggs in two shipments (ten cracked and gross in the first shipment. AND then, I candled the other eggs I received from two different ebay sellers- silkies and easter eggers. Total= 28 eggs. THere were very many that I couldnt see anything in but I didnt toss any- its only Day 7....my complaint is most of these eggs are so darn porous, its all I see. I don't know if that happens from a calcium deficiency or what- but I know it doesnt end up that great when it comes to hatch day. Are silkie eggs normally so pointy that you cant really tell which is the large end? I had to candle most of them to see which end had the aircell when I first set them. Today is the first time I opened the incubator. I think that automatic turners are the best things ever- I am hooked for life now. I need one more. My temperatures have been right at 100.3 center of the egg...beautiful not having to open that 'bator at all. If I don't have a good hatch out of them I will, well, I will order more eggs but that is beside the point. However, and the only reason why I keep my finger off the 'buy it now' button on ebay is because I have eggs coming from a seller on here. I am confident that those eggs will be much better than the others I have received. I am most frustrated at the porousness of the these eggs. Can anyone shed some light on what causes that?
