Hello, I have a flock of 15 hens that free range in a large fenced yard. I currently have two hens with baby chicks, and they keep attacking each other! They never fought before they had chicks, but now they go at each other like a couple of roosters. They have all the space in the world, but as they wander around with their babies, the fight when they encounter each other. I'm wondering why they are doing this and also if there is anything I can do. I'd like to continue to let each Mom/babies free range.
