Determining if there is development

[happywithhens]

This is my first time incubating.. my temperature and humidity have stayed pretty controlled. However, I’m nervous as a bunch of my Eggs all have this ring around them. Does this mean these eggs won’t form a chick? Please help!

These eggs are on day 12

Sadly, blood rings can mean that the embryo has died. So sorry!

 

[WVduckchick]

So sorry, all those are gone.

Is that normal to have that happen? I have about 8/28 like that...

Also I should just toss them and take them out of the incubator then, right?

Yes you can safely remove those.

Blood rings happen sometimes with heat spikes, eggs shaken from shipping are prone to it, or young pullet eggs sometimes quit early. The ring happens when the blood vessels die, gravity just makes them all gather together.

I actually just counted it was 17/28 that have blood rings. I’m so
Bummed, the temperature and humidity have been on point.

Are you going by the incubator gages or did you get separate meters and verify them for accuracy?
