Air Cell Questions

[peanutfeather]

So I've been candling everyday of my eggs.
Honestly I don't have an idea of how old every egg is.... about 3 eggs have veins, and other 5 are just beginning to have almost the entire egg full with a darker yolk color - but no veins.

But there are a couple of eggs who just have the yolk but it seems as if the yolk is a darker color and is bigger than normal. Are these eggs growing? Also their air cells are gradually growing each day.

But my question is are eggs that have a growing air cell considered fertile? Or does a growing air cell happen to every normal egg?

The air cell will grow on every egg as the chick develops and or the egg loses moisture (this is normal). Just make sure you have the proper humidity range so they don't loose to much moisture.

From what I've seen, the air cell will continue to grow in an incubated egg, even if it's not fertile.

Thinking about it, the air cell will continue to grow, even in a non-incubated, non fertile egg. That's where the float test comes from....an egg with a larger air cell will float, a smaller air cell will sink. Older eggs have larger air cells, even store bought non fertile refrigerated eggs.

This thread helped me tremendously when I first started incubating. Hopefully it'll help you too! Good luck!
