Candling Dark Eggs Question

[rhino533]

I'm on my 11th day of incubating Chicken Eggs. I've done this before (this is my 4th incubation so I'm still a beginner) and had no problem in the past candling the light brown eggs. This time I'm having real trouble seeing inside the eggs because the eggs brown not light brown. I have a pretty powerful LED light and this is what I can kind of see in the eggs. I see the air sack and then more than half the egg is dark and the small point is lighter. One thing I can slightly see are veins. The veins are not in a circle like when bacteria invades the egg but are more like a web shape and I can only see them where the egg gets lighter on the smaller end. I'm pretty sure that means the egg is fertilized but I just can see the chick. I have 8 light brown eggs and 15 brown eggs. One of the light brown eggs was a dude and 7 are fertilized and can see the chick. The 15 brown eggs I can only see what I mentioned above. All the eggs are from my chickens. Any advice would be helpful. Thanks

Your eggs are definatly fertile.
Sounds like you have some growing babies inside to me

Web shaped veins are good news!
