How to Tell a Fertile vs INfertile Egg (Pictures)

[Tailfeathers]

Typically, it is pretty much agreed that 3 weeks is the max the hen will remain fertile after a rooster has been on her. I would think it is more likely that your 15 week EE is the culprit.

God Bless,

Looks to me like one of these is fertilized. Thoughts? They've been away from a full grown rooster for about 5 weeks. We may have a 15 wk old that might be a rooster...not sure yet. I suppose if these are fertilized, that would close the book on that question.

Does not look fertile to me. The shadow around the blastodisc is not the bullseye, IMO. It's a white ring you're looking for. I've had infertiles that appear that way often.

Wow that is great.

Question. Can you tell without breaking it?

I dont think you can tell before cracking the egg unless you incubate and start to see veining...

Cynthia,

What wonderful photos! I wonder if I could ask permission to use them for an article I am writing (with attribution, of course.) If so, would you let me know by PM or email me offline?

Thanks very much,
