I just got a new rooster, about a year old. I did not have any roos til now. I put him in on saturday and checked the eggs this morning, now there are only 2 hens with him now but both eggs had the white dot and their eggs from saturday did not have any dots. I heard it can only take 25 hours but really???
 
Wow! Brings the whole idea of stud to a different level!

to be quite honest I have no roosters and I see white dots and bullseyes in my eggs all the time I think its a bunch of baloney and do not believe there is really any true way to tell a fertile egg.
 
Well mine certainly never had it before. I do know he is doing his manly duty and his former owner said he was quite fertile. I will be checking myself in a couple weeks to see how they are when I have a free incubator.
 
There's always a white dot on an egg yolk. Sometimes, you have to look at the underside of the yolk to see it, but it's always there. That is the blastodisc. When it's fertilized, a ring forms around that dot and it becomes the blastoderm, the developing chick.
