My gander, Harold, killed one of my hens. So I moved him into a different pen where he could see his female but not get near the chickens. He's managed to get back in and has gone after the hens again. I'm afraid he's going to kill another. Can you tell me why he's so aggressive towards the chickens? Maybe I should just set up an area just for him inside the yard that he can't get out of? I'm new to geese and I got a pair specifically for noise makers and maybe to chase off a critter that might make it into the chicken pen. Harold and Maude are Toulouse geese. I was told the Toulouse was the least aggressive of the geese breeds. Was I misinformed? Thanks for any ideas that does not involve killing him.
