I'm almost positive they haven't been together mating. I'm going to try to pen them up. I'll keep you posted and thanks. By the way, one of my hens is blind, have you ever heard of that. She does fine though.
As @feedman77 says, just because you didn't see the matings it doesn't mean it didn't happen. It is best to separate one tom and the hens as multiple toms in with the hens can cause reduced numbers of fertilized eggs and injury to the hens.
You can crack one of the existing eggs to check for fertilization.

You should definitely separate the blind hen from the toms as it would be irresponsible to breed her.
