How old is my egg?!

[1011023]

I have 15 eggs in my incubator, a bunch of different breeds, and this is they're 3rd day. I candled them this morning and it appears that one of the eggs (speckled Sussex) is far more developed than the rest. I bought the eggs from a hatchery, could it be that the egg wasn't collected until a few days after it was laid? This egg has a lot of veins and you can see the embryo move inside. The rest just look like yolks. How old is my egg and when should I stop turning it? Are my other eggs fertile? Also, in the advanced egg the yolk stays to one side of the egg, is this a problem?

I'm new to this so don't know much, if there's any tips you can give me they'll be much appreciated!

Thanks

day 3 is too early to candle - all you are doing is risking damaging eggs.

the egg with life in it may have been exposed to warmth along the way - check its progress on day 10 when you next candle.

good luck
