when are they visibly fertile?

[Chicken Ducks]

4 days ago I placed 8 day old eggs into the incubator. 15 eggs in total.

I've noticed that 2 of the fresher eggs are visibly fertilized. However I cant see anything happening in the other eggs.

So after 4 days, shouldn't I see some blood? Or should I wait another 3 or so days?

From what I've gathered, it is better to wait until day 7 to attempt to distinguish feetile from infertile. Personally, I won't cull eggs until day 10 unless something is seriously wrong.

What color are the eggs? White eggs you can tell earlier. I would wait until they where 7 days and try again. That is when it is really easy to tell.

White. 2 of the fresher eggs have started growing veins. The rest haven't really changed. What are your thoughts? Thanks for replying

I would wait a little while longer. Some eggs tend to grow larger veins faster than others. So the other ones may be viable but just not showing up yet.

I set eggs Thursday and candle for the first time on Tuesday the following week. So that's 5 days. I can tell for sure with my candler if they are fertile or not.

If you don't feel certain, candle at 10 days and toss any that don't show growth. By day 10 it's obvious.

You should see some evidence of veins at day 5. I like to wait a few extra days in case there is a late bloomer.

Sounds like you have a lot of duds.

Sorry!
