I am new to chickens, I had two silkie hens given to me built a great coop and run for them and then got a young silkie rooster. The other day, in the middle of the day, I found my one hen at the front of the pen dead the rooster close by but no blood on him. She had head trauma I've never seen him do anything really aggressive, chased slightly, but I'm guessing it was him and I'm devastated. The other hen is my layer and seems fine. The deceased was not a layer and I worried occasionally she wasn't well, but thought she was getting better. I had cured a sore foot and she seemed ok. Do I need to rehome this guy???
