How do these look? I am pretty sure I see a blood ring on one but hoping a few others are developing

Since you're on Day 7, eggs 2 and 5 are clears. Either not fertilized or stopped, but they're not developing. I'd toss them. (image 8420 and 8439).

1, 3, and 4 look good. I think I see an eye spot in 1. (images 8414, 8424, and 8434)

Have fun incubating!!!
Thank you! That’s helpful. I had doubts about the same ones that you mentioned. It looks like I missed posting pics of my 6th egg, it’s another dark speckled one that looks really similar to the third one so sounds like it’s looking promising too 🤞

I’ll probably update next week, it’s my first time incubating so this is all a learning curve for me! Thank you!
 
I am not sure about picture 8420. Looks like there is a blood ring in which would not be good. Don't have a 360 degree of the egg. The background light makes it harder to see too.

I found out that the yoke moves easy in the egg when you rotate it if they are not fertilized. Fertilized eggs are more steady when you rotate the egg to see it from all sides.

I candled the brown eggs at day 9 and I was able to see the chick moving if you patient enough and look for the dark spot in it. Really cool. You need a good egg candler and a dark room.

Ok I followed recommendations and candles again in the complete dark! I wrote numbers on them. If you look back at my original pictures I missed including egg 4.

So egg 1 was pic 8939 - I don’t think it was fertilized maybr

Egg 2 - pic 8414 - had the ‘eye’ in earlier pic. Think I can make out veins in the dark??

Egg 3 - 8420 - the possible blood ring is I think even more visible, not feeling hopeful about this one, debating about discarding.

Egg 4 - missed the pic of this one earlier, it’s darker and hard to tell. In the dark I am wondering if there’s a ring on this one too?

Egg 5 - pic 8424 from earlier. This ones speckled and darker too so I struggle with it.

Egg 6 - pic 8434 from earlier and wow the dark made a big difference with this one! The veins were so visible, my camera maybe didn’t capture it as clearly as my eye but I could see lots of veins.

Flip the eggs over and shine the light in the fat end of the egg...not the pointy side.
 
At day 7+, you should be seeing veins, yolk should be attached to the side of the egg by this point, and not moving around when you move the egg. If yolk moves easily around from one end to the other, is not attached to the side, you can't see veins or eye spot, then odds are good it's dead at this point. For those I'm not sure on, I give them another few days to a week, and then the difference between the growing ones and the dead ones is very obvious. Rotation of the egg when candling in a very dark room and looking through the air pocket into the egg are key. I use my hand to block out all light except what goes into/through the egg. At this point you should be seeing fetus movement, veins pulsing, etc. Also consider higher lumen flashlights to see through those dark shells. I've candled FBCM shade 7-9 eggs successfully, but you have to have really strong light.

Ok, eggs 2 and 6 I can see veins clearly on.

1 I see nothing and 3 I think has a blood ring, so I think both those are not growing.

4 and 5 maybe my candler isn’t strong enough. Or I haven’t blocked enough light. I just can’t tell with those darker ones… I’ll try again next week.

I haven’t tossed 1 and 3 yet. Are they ok in there until next week when I candle again? I guess I’ll candle them again to be sure but I’m not holding my breath. I assume I’ll be tossing those two next time I candle?

I generally candle once on Day 7 and again when I go into lockdown. Day 7 is just for curiosity, I do not toss any eggs at that time unless there is some obvious significant issue. I mark red for any that I think are no good and black for the good ones. My eggs are blue and green and it can be hard to see inside. When I candle at lockdown I remove any that are obviously not going to hatch. That is not because I am primarily worried about them exploding but to reduce the numbers of eggs I need to follow during hatch.

The risk in leaving them in is that they get bacteria inside. The temperature in an incubator is a perfect temperature for bacteria to multiply and the material inside is a perfect food. If your incubator was clean to start with, the eggs are pretty clean, the bloom is still intact, and you kept your hands clean when handling the eggs it is unlikely bacteria will get inside. If bacteria gets inside the egg should start to stink through the porous shell. When you open the incubator (maybe to add water) do a general sniff. If you smell the rotten egg smell sniff each individual egg carefully to carefully remove the culprit.

This is my methodology. I have made mistakes in which I mark red on Day 7, but very few anymore after I got some experience. I've never had an egg explode in the incubator, actually never had one go bad. I have had a bad egg under a broody hen, a horrible situation.

I cannot give you any guarantees, anything can happen. Do as you wish and best of luck!
