We adopted a Speckled Sussex Roo and hen over a month ago. He had been hanging back not really coming close when we handed out treats or feeding the girls. He came from an iffy location possible cock fighting breeder. We were hoping for chicks from the pair. Anyway things were going fine with integrating them into flock, girls paying him attention, grooming etc until the day before yesterday. His protective instincts kicked in he didn't like us ( my great niece and I) picking up and examining the girls. He ran out of the run and we took off to get him. My niece got close and he flew at her flogging her. I had my herding stick got between them pinned him down and he really started fighting pecking and kicking. We examined him checking for lice mites which we found he did have. He was furious. We got him back in the run but kept challenging us. I told my niece she couldn't go in any longer without a stick. Yesterday I was by myself to refill feeders, check water and prepare to shake and bake them - apply Sevin for the mites/ lice. I filled the first feeder he was sitting in back of run calm, the girls were crowding around me for pats and treats. As I started filling the second feeder he was moving toward me, no feathers fluffed, no warning mantling, no sound. If it wasn't for my hood being up and raising my arm he would have gotten the side of my face. He had knocked my glasses askew and a 1" scratch on my right hand. He started flogging and jumping at my legs attempting to drive me out. Stick in hand I drove him back but he kept coming trying to get a better jump at me. I pinned him down with a smack and he became totally possessed. I grabbed him by neck and wing, grabbing his legs headed out of the run he had lived up to his name POS (pot of soup). My Sister heard the commotion and got me the hatchet. He was still fighting I have never seen a Roo turn so violent before. After the deed was done I realized he probably wasn't safe for eating as he had been wormed and was still in the toss out time period. But having him in a small confined area I couldn't see it being safe for any of us trying to feed or water him without being injured. My niece also likes to sit with the girls playing music from her ipod and handling them, with that rooster she could have been seriously injured if he thought she was some type of threat. I ended up plucking his pretty feathers and examined him. He had a metal tag in a wing webbing for an immunization and on his breast there was a thread stuck into his body. I tugged on it and it was definetly attached to something in his upper body cavity. His skin condition was pretty bad. He had been on a diet of just corn and alfalfa hay when we got them. They didn't even know what feed pellets were. He had gained some weight but skin color was still yellow but not as big bird yellow as it had been. Skin was really rough evidence of past injuries, rash and strrange skin tone on thighs. The back had the start of a bruise where I had smacked and pinned him down with stick. Rather then finish up a necropsy and find out what the string was attached to I just disposed of the carcass. I was still so angry! I checked on the girls they were upset but not as bad as I feared. The sussex hen now has no protector and has to find her place in pecking order. After they calm down tomorrow or so I will do the shake and bake with the sevin. The crazy Roo didn't give me a chance to make him a part of the flock and recognize us as dominate. I'm done ranting now......thanks for letting me.
