I have a slightly inept polish crested rooster, meaning he crows, but other than that, does not seem to be very roosterish. And a flock of various breeds of hens. What are the odds that he is not "performing his duties" as a rooster? I've seen him mate with one chicken a few times, but how would I know if he was doing the deed with all of them and whther my eggs would be fertilized? I am hoping to hatch some this spring.
