All of a sudden my drake started trying to kill one of my roosters. It started this mornin, my dad took the hose to them. Then when i got up he yelled for me and they were going at it again. I grabbed my roo and ushered the drake into the pool. I had to go for a bit and when i got back i asked dad if they got into it again, he said no. Since i was gonna be home i let everyone out to graze. They started in again. I grabbed the drake and held him for a couple minutes which he did not like. Then i set him down. He then goes after the rooster again, grabs him by the hangy thing under his beak and is trying to rip it off. Im trying to catch them but they go under the porch then they come out and i try to grab my drake but he takes off and the rooster starts chasing so i grab him and hang him upside down by his legs, then i set him down and all is well, they havnt fought since then. I dont understand what started this brawl. He isnt going after the other 2 roosters. I thought maybe he was protecting his 2 girls from the one roo, but the other 2 roos mount the ducks more often. Im at a loss.
