Egg candling pics and questions from a newbie

[SpeckledPullet]

I am at day 4 and 1/2 and had a few questions about candling. I have been candling daily to try and learn and get experience under my belt. Today was the first day I really SAW obvious changes in some of my eggs. Most of them have a cloudy mass taking up most of the egg. If I look VERY closely, I can somewhat make out a small dark dot. Most of the eggs have a dark dot about the size of my pinky tip. I assume these are healthy, developing embryos. However, a few looked similar but the dot was even smaller. The dot was maybe 1/4 the size of my pinky tip. Are these just late bloomers, or are these blood spots? My camera was not good enough to pick up on what I am talking about. However, here is one of the eggs with the larger dot. Most of my eggs looked like this. Sorry, the camera is BAD. It is more clear to me, but the camera just annot pick it up well. I circled wher I can obviously see a dark spot.

I also had two or three that looked porous. Are these too porous to be good? I can see cloudy masses in most of the porous looking eggs. Are they okay to leave in the bator?

And, one or two looked like this. Is this a dud?

Thanks! I will try to candle again at day 7 or 8. This is all so much fun! I am really learning a lot. This is my first set of eggs ever.

Have you seen the candling progression thread?

You might want to try and compare what you are seeing with the pics in the thread. 4.5 days is about 100 hours.

Porous eggs should be fine left in, don't cull anything from the bator till at least day 10 to be sure on development.

Shine your light directly down on the fat end and kinda rotate the egg keeping the light on the fat end. You should see some veining. If you do that is very good. Silkiechicken's candling documentation is very good.

Thank you both. I think I just didn't have a good enough light and it was too early to see much in my brown eggs. I just candled again today, day 10, and was finally able to see something closer along the lines of what silkiechicken's pictures look like. Great pics, silkiechicken!
