I have been suspecting my sultans (hatchery quality) of being roosters for a while based on their behavior but now I'm really starting to wonder about them. They are about two years and half old and though I've never heard or seen either crow I do see them stand off in typical rooster fashion frequently. To top it all off, when I was making eggs just now one of my eggs were fertilized! Yes, I know it was fertilized. It had the very distinct bulls-eye in it instead of the plain white disk that the other in the pan had. The thing is, other than these suspected roos, I have no other roosters since I dispatched my last one last summer for crowing at three in the morning. So, here is my question, has anyone ever been lucky enough to have a silent rooster?
