I had to send my rooster away for a couple months during the summer because my neighbor was annoyed. Now that the weather is cooler and everyone keeps their windows shut I've brought him home. I was expecting to quarentine him for a week to prevent any fighting, but it seems the hens may remember him and he the hens. Even the chickens (chicks) that I've added to my flock since his departure don't seem to mind his presence. It's like he never left at all! Is this normal? I did not think they would remember each other. Should I still seperate him tonight when there is no supervision?
