I used saddles on a couple of my hens, when I only had a few hens with my rooster. My advice is to get a color that blends in somewhat with the color of the hen. Avoid really bright colors. I had a bright purple one that I put on my hen and she was terrified of it for some reason. Every time she'd look around behind her, she'd squawk and start running as fast as she could... I finally caught her and put a black one on her instead (she's gray) and she was fine with that one. It's quite possible that my hen is just nuts... Another of my hens was fine with wearing a bright purple saddle. But I thought I'd tell you my story anyhow, just in case!
