I have kept chickens for a while now. I lost my sweet Salmon Faverolles roo two years ago. I was devastated. He was my best friend. I spent hundreds of dollars at a vet trying to save him. He got surgery to remove his toes, and antibiotics. It didn't work. My mom took him to the vet where he was peacefully euthanized. He was one of two chickens I ever lost. So, recently, this November, I decided to get a little bantam to settle my hens, who were picking on each other. He is a bantam Mille Fleur D'uccle and he was such a little sweetheart. I loved him, played in the yard with him, snuggled him. I even brought him to a preschool and had little kids pet him. Sadly, my pretty little bird developed frostbite. So, for a while, l took him inside and kept him in the basement, especially at night. He would crow all day, and sometimes at night. I think that is what made him go crazy. He has turned vicious. He attacked me 3 times, and my sister and my father once. My dad has a horrible gash down his hand just from trying to change the water. He was raised very nicely, and lived in a very nice farm where he was handled daily. Please, l'm desperate. If he keeps this up, we might have to give him away. He was such a sweet little fellow too. Do you think there is anyway this behavior can be undone? I love him, and he is a pet, just like a dog or cat for me.
