Rooster?

Yep, assuming he's not sterile.

Is this common? I'm new to all of this.

So if he is in with all my hens, chances are I have some fertilized eggs on my hands?

Probably. There really isn't any difference between fertile and infertile eggs until incubation occurs.

Lots of us keep roosters with our layers. I've done so for 20 years and never had a nasty surprise when I cracked an egg.

chickens are different than mammals with regards to reproduction. Chickens are much easier to manage, IMO. The rooster can mate with the hens all he wants, and yep the eggs will be fertile. But, embryonic development won't start until/unless the eggs are held about 100 degrees for at least 3 days. Up til then, you really can't tell the difference. There is a subtle change to the yolk, but it's difficult to see and takes an experienced eye. No difference in taste, etc.

I wouldn't say its common, but it does happen from time to time.
