I'm raising three chicks, all pretty different ages: 1 5-week old Easter Egger, 1 4-week old Maran, and 1 2-week old white cochin. The Easter Egger pecked the Maran's vent to the point of bleeding, so I dressed her vent wound and I've separated everybody into three separate brooders. Everyone hates being alone and is crying loudly, even though they can see and hear one another. I'm worried that the size differences are going to continue to be a problem until everyone evens out. Is there anything I can do to make the separation easier on these girls?
