How young can a rooster provide viable hatching eggs?

What is the youngest rooster someone has successfully hatched eggs with?

I can't keep roosters on my property long because we're in a neighborhood but I really loved the frizzle rooster I just rehomed and I'm considering collecting all of my hens eggs for the next few days and putting them in the incubator to see if any are fertilized. I was just curious what my chances are that any of them are fertilized because he was so young. Thanks!

Crack a few open and check them for fertility.
If he was mating your pullets/hens regularly before you rehomed him, they will remain fertile for at least a week, likely longer if he was hitting the target.

I tried checking one and I'll be honest, I don't think it's fertilized but I'm kind of just being extra hopeful at this point. I never actually saw him mount a hen so it's possible he wasn't interested yet.
I just thought I would ask what others have had success with!
Lol, I May just save some eggs for a few days and see what happens. I'll know in a week one way or the other I guess!

He was about 4.5 to 5 months old. I just cracked a couple more open and surprisingly my bantam cochin's egg looks fertilized! It's hard to see in the image but the top one has a clear bullseye. Most of the eggs look like the one on the bottom with just a white dot. I'll give it a try and see what happens!
