Contrary to rural legend, no dog can tell the difference between the scent of a rooster and of a hen.
A vet friend had this really super yellow lab, Belle. She would consistently flush roosters, seldom a hen though you know there were a lot more of those around. Neither of us really believed she could tell the difference by scent but we could find no other reason for her defying the odds so soundly. So who knows? Could make a case for roosters and hens smelling differently, but getting a dog to discern the difference would be something.
