Fertile or not? Day 4 candling

[Cwillenburg]

Day 4 of my first time incubating and it looks like 3 of my eggs aren't fertile. What do y'all think? The first photo is one that is developing

I saw veins, so I do think it is fertile.

All three of them? The first one is for comparison

The last three don't look fertile. Candle again on day 7 and if there are no veins, chuck them.

second and last may just be behind, as mentioned double check day 7. The third is definitely not doing anything. Usually I can see the beginnings of changes around end of day 2-3, darkening of the yolk, sometimes a darker line, but no veining til day 4. If any of those are blue eggs, I do find they’re harder to see details through early on.

All of them are blue lol

Agree, wait until day 7 to be sure. Blue eggs can be as tricky as the dark brown ones.

That explains a lot then. Haha. I incubated over 2 dozen Legbar eggs (bad shipping experience for all) and it took forever to be able to say for sure whether or not they had a blood ring or were just hard to see into! Lots of blood rings but it was really hard to tell until they settled into a very obvious ring.
If you have hot/cold spots in your incubator that could make some slower to develop too.

Had the same experience with some ameraucana eggs last year, could not see blood rings until day 10.
