Ive searched and cant find what an egg candled will look like at day 21, ive heard you will start to see a thing moving into the air sack? but not sure.. The eggs are all DARK!! cannot see anything on the big side,but right next to the airsac you can see blood veins. The eggs dont stink,theyre not weeping or anthing... just dark.no light will shine through for the most part. Last week i could see chicks moving around in them but now just dark...Is this a good thing?????????? I have heard no noises from the eggs.
