I haven't raised chickens for a while, but I will again, soon. When I had my small, mixed, flock several years ago, I made a point to handle them quite a bit while they were still babies. Then, as they grew older, I found it much easier to pick them up at night after they had roosted. If I did that every once in a while, they stayed tame. They are at their most vulnerable at night. If you pick them up then, and are gentle and loving with them, they will remember that for a while.
