OK, here's a roo Q. When I go into our pen and handle our hens, I have to be careful that I put them down away from our young Speckled Sussex roo because he will rip their feathers out, especially if they raise a fuss when I'm holding them. He is the king of our flock even though we have several roosters. All were hatched this spring so they are 2-3 months old. I'm keeping an eye on him. I hope he does not become agressive toward us. He'll have to go.
