Ummm no,,, I would suggest trying to find the reason behind the aggression first, if you have no hens sitting, you might just separate the two bullies because alone they aren't nearly as brave. Also, you could rehome them if you have another drake that can take care of business but is not as mean. Try getting rid of one first, see if that takes care of the problem, if it doesn't bye bye to number two and get a drake that has better social interaction with us hapless humans. There is nothing like being bullied by a feathered monster that weighs less than 10% of our weight!
