Old eggs

I put in 30 eggs that were 3-4 weeks old. 6 made it.

 

Just put another six eggs in the bator,they are a week old.Is that ok?

 

If they are kept cool, up to ten days is the ideal. From there you will start to lose out on hatchability.

I have done eggs that are 20 - 22 days old and got a 30% hatch.

 

16 days i waited with my current batch, 17 out of 20 are viable!!!!
