15 day old eggs?

[DaveMorehouse]

Hey group.

I have saved the eggs from my three hens (Plus one roo) for the last fifteen days. Last night I put them all in the incubator. (LG with heat/fan/egg turner) I meant to only keep ten days worth of eggs but time got away from me and I didn't date them as I saved them. Will the old and like dead eggs affect the hatch rate of the live embryos as they exchange air through the shells?

I have only hatched one batch before and didn't have any luck trying to candle them. There were a few that I could see veins in but most of them just looked the same to me. I really am a newbie with quail. Any advice is always appreciated.

Thanks,
Dave

Leave them for 2 weeks candle again, I have had eggs much older than 15 days hatch.

Thanks, DuluthRalphie. That is helpful. I had hoped someone would have had experience with older eggs. Thanks again, Dave

The hatch rate goes down, but I have never had it hit zero, yet...LOL
