That’s a good idea! We don’t handle him much, if at all. Is there a good way to catch him without freaking him out? (This is our first flock and they’re about 5 months old so very new to this!)
Wait until after dark, then grab him off the roost. He may freak out at first, but most chickens settle down fairly soon if you hold them securely but gently, and maybe talk softly to them.
Just what I was going to suggest -- taking him off the roost at night.
I find that they calm down nicely if you hold them like a football with the body on your arm and the head in your armpit.
It's easiest to do wing clipping with two people, a bird holder and a wing clipper, but you can do it yourself if you sit down with the bird on your lap.
