My first time incubating....some 11 day questions....please

[BBloves]

I have been very unsure candling. Only because i'm never SURE what i'm looking at, my eggs are mostly light brown. Today was day 11. When candling this morning I can see a lot of movement inside the egg. It is so dark on over half the egg so it's difficult to see the embryo. Is this normal, can I assume everything is going good? My porous looking egg has the same movement with a dark shadow moving around. Please help. Thanks so much

This is a very helpful link to show what your eggs should look like at different stages of incubation: https://www.backyardchickens.com/a/candling-pics-progression-through-incubation-of-chicken-eggs

The fact that they're moving is a good sign.
