Remind me again... When do you start counting incubation days?

Here are the photos enhanced

The first photo does look like a blood ring forming around it, but I wouldn't be 100% sure because I'm looking at a pic and not the real thing. I can't tell what's going on with the second one and the last one looks like a double yolker to me.

I just learned I candled the last two backwards..

On the blood rind looking one, any advice on how to know if it has visible blood pooling?

It is much better when you candle from the air cell. You see things more clearly. If you candle from the top and it's a distinct ring going around the egg and you see no other veining, then you can be pretty sure that's what you are seeing.

The bottom one looks so round it's hard to tell what end is what...lol

So I read somewhere that you could judge good vs bad eggs on day 14-17 just by weight. Have you experienced this?

Never heard it and I don't weigh. I'm not sure how that could be judged by weight as some eggs may have lost more moisture than others but all could still be alive.

I think she is weighin them by hand. Light vs heavy

You can definitly tell the difference in weight between a non-fertile egg and one with a decently formed chick inside. The density of the chick is greater than the density of the basic liquid of a non fertile egg and therefore heavier. There is an actual mathamatical formula to show this but I don't remember it off hand. I would not rely on it as a good method to detect "bad" eggs though. Candling is by far the best method.

Thanks!

Eggs go on lock down Friday. Do I replace the plug?
Fill both or one trench with water?
