If you want some buttons you will have to keep them in either a cage or aviary. They truely are tiny, with day old chicks being able to squeeze themselves into trouble with wire as small as 1/4" square. If you go the cage route, keep it low in height, about 12" is good. Buttons that are frightened jump UP at an explosive speed, having the cage at only 12" will limit the damage to their heads/necks. You will still get bloody heads when you scare them, but they will be fine. After a while they get use to you and things get a lot better. If you get young ones be sure to grind the feed for a week or so, they have a tough time with crumble size food at that age (1-2 weeks). Marbles in the water is a MUST, they WILL drown as chicks in any waterer (even the one's designed for chicks). And if they don't drown they soak themselves to the point that they will pile for heat and then you lost half of them due to suffocation.
It's not all grim however, I have raised thousands of buttons and they can tame down really nice. They will never make it for long outside (free range/chicken coop) however.
Hope that helps!
