Egg question!!
Tonight will be night 8 of incubation of our one single pekin egg (dad was a khaki Campbell). I don't have a ridiculously bright light, only the flash option on the camera on my phone, to candle the egg. It's pretty obviously not bright enough, but I can sort of see in the egg - I've very gently candled it a few times. It definitely doesn't look like it did when I first put it in the incubator - the air cell is rather large, and at the opposite end of the egg the yolk or what was the yolk is very dark and takes up *almost* 50% of the egg. The light isn't really bright enough to see completely though it at all, it just looks like a dark spot. It's no longer circular, more of a heart shape. It doesn't move hardly at all when the egg is being turned, just very slightly. The egg is also noticeably heavier than a fresh duck egg. Are these signs that it might be fertile and growing? It does seem to look different than it did a couple days ago, but I'm worried that the reason that it looks different could be because it's rotting..... Hopefully not!! Thank you!
