That's awesome. I bought 4 "day old" chicks about 3 weeks ago. Two are definitely older. I put them in a plastic baby pool with pine shavings in it one warm day to let them experience the outdoors, but they didn't touch the ground. I heard it's good that they touch the dirt to expose them to coccidiosis just so they can build up immunity. But I thought the little ones were too little yet. Maybe they are old enough now. I just don't have anything to reign them in with and don't want them to go too far from me.
They can be a challenge to catch... my kids are really good at it. I don't think it's good to baby them too much, personally. I travel all over the world and you see baby chickens doing just fine with very little care. I like to get them in the yard, at least for part of the day, as soon as I can. As long as they have a place to hide and some shade they seem fine.
