I recently got a pair of two year old geese from someone who decided he didn't like them anymore. Everyday, I sit on the tailgate of the truck and watch the geese and chickens. they are all free range. The gander, his name is Quinn by the way, walks up to me, and starts rubbing his bill on my boots and legs. he does this and then starts nibbling. he also tries to climb up up on my boot. He then gets more and more agressive in his biting. Why is he doing this. He does this both before and after he is fed. He also makes no noise whatsoever. What does this mean? is he looking for food on my leg? What is he doing??
