I have a 5 month old leghorn rooster and barred rock hen. They have a very nice large coop. They free range during the day and come inside at night. Also in the coop in a separate area are 15 one-month-old hens that I am integrating. They have been together for about 10 days now. They can see each other but not touch. Today I went out to the coop to let the roo and the barred rock out for the day. I shut myself in the coop and fed and watered the little chicks. When I opened the door to come out the roo came after me very aggressively. I grabbed a shovel and held it up and yelled at him. He tried this three more times as I made my way back to the house. I was freaking out. I did what I have been told to do for a bear attack, trying to make myself appear big and threatening. He was not intimidated in the least bit, and kept running after me. I fiinally made it inside the house, phew. Now my rooster is circling the house, cockadoodle-dooing like crazy, moving from one entry to another. I am afraid to go outside. I did a search and read that I should grab this guy by the feet and show who is in charge. I am desperately afraid to do that. He is big and I am not. My husband is the one who usually herds the chickens in and out, he is not home today. I need to leave and pick up the kids in a couple of hours. Aside from grabbing my gun, any suggestions???? He has never acted this way before. Thanks!
