My white leghorn kept picking at others' tail feathers, and I worried she might start doing harm in time. So, I separated her for the first time tonight. They are out in a giant run all day, but we still bring them in at night (no coop, yet). They are 5 1/2 weeks, mixed breeds. Inside, they're in a 2.5 x 4 dog kennel (with open bars, not the cargo-type... the dog-crate-training type). So, I put in the divider panel used for small puppies (the divider is just like the rest of the cage). She has 2 square feet to herself, with a perch, food and water. She keeps charging at the divider, trying to fly over it, push her head thru the bars (her head fits smoothly, but not her shoulders, so I'm not worried about her getting stuck). Will she calm down eventually? Thanks for any words of support.
