I have 4 laying hens right now and am considering raising some turkeys next year. Will they be able to free range together or will my hens get picked on? Also, my hens are not flyers, they need a step to get on their roost, just a stall door! There isn't much room, will the turkeys push them out, or will they roost in the tree? I wanted to try maybe 6 turkeys. Any thoughts?
