Apologies in advance, as I'm going to get a little philosophical here. I do not believe roosters mate hens because they are "in love with" them. (I assume you're wondering if this is mating behavior.) Nor do I believe they mate, or breed "to perpetuate the species" or "propagate their genes," at least not in their minds. Breeding is strictly hormonally driven, they do it because they have to, in the same sense that they eat because they are hungry. Because you have handled this cockerel since he was a chick - and he is a cockerel, not a rooster - he sees you as part of the flock. Therefore you fall into one of two categories: rival or potential mate. The way he grasped your hand is the way he would grasp a female he intends to mate, IMO. If you don't allow that, you become the Other - a rival. And as such (again, IMO) he is going to start trying to get rid of you - by chasing, flogging and challenging you with no holds barred. It could get ugly. One of you will have to go.he in fact.. in love with me...?
