I have four three-month old chickens that I got at a week old and that were supposed to all be hens. It turns out two are roosters. Someone gave me a hen from the same batch of chicks and I tried to introduce her last night. This morning, the two roosters were trying to kill her. I found a home for the roosters, luckily, and I was going to wait a few days to try to introduce the new hen to the other two hens. Any advice? Should I keep the new hen in my brooder box in the run for a while? I hate for her to be all alone again tonight since the roosters are leaving in the morning but better lonely than dead. It was so traumatic!
