I just wanted to throw this one out there for anyone who might know the answer. I went to buy som birds to train my Springer, and the guy selling the birds told me that a hen pheasant, when in heat or laying on eggs (not sure which) has no scent. He said it was a natural defense against predators. Is this true? He told me I could get hens like this when he had them available, and said that this can be very affective for training a dog. Any thoughts?
