ChickenCanoe, a friend of mine built stacks of 2x2 or maybe 1.5x1.5 cages for his annual testing. The morning of, he goes out before light and removes each from the roost and places in a cage. He is possibly the most organized person I know when it comes to chickens.
My birds are mostly docile, they don't like being caught but they can be. The Silkies are easy. Last time mine were tested, last fall, I had most of them out in smaller runs so there wasn't a lot of room to escape. The only ones I had at the time that gave me trouble were the Fayoumis, which are probably most like the Penes in temperament with regard to being caught, and I was glad I only had the pair at the time (I don't have them any longer, had to make some room and sold them to someone who wanted birds well suited to free ranging - they most certainly are). I had them in a 3x8 run with a roof, they flung themselves against a corner, and as I would reach for them they would try to fly over my head - one managed to do so twice, the hen.
The less space they have and the calmer I stay, the easier it is on the birds and me. They don't test birds younger than 4 months, and here at least, they won't disturb nesting hens or hens raising chicks. They are usually easy to work with and very good at handling birds. In CO they are not allowed to own their own birds, and suit up with boot covers and the like.
