Once they're outside? My 6 week olds are in a 20x15' enclosure. There's some deep litter, weeds, gravel (pea sized, too big for them to swallow, I'd think), and I'm wondering if I should still be providing grit, or if they will find what they need on their own. They forage but also have food and water at all times. Oh, I do also have a pan with sand for dust bathing (which they have yet to use).
Granite grit. I buy it for my chicks. #1 size (1/16"). Sometimes it's called "fine" grit. The back of my package says that chicks aged 1-3 weeks get #1, and that chicks aged 4+ weeks old should get #2 (3/16"). For whatever reason, I feed my chicks #1 until about 10 weeks old, then switch to #2. I am very loosey-goosey on the age, though. If they have graduated from soaked field peas (or sunflower seeds) up to hard field peas, then I think they are ready for #2 no matter what age they are.
The bag says that the chicks can have the grit "free choice" at 2 weeks, but before that, it should be sprinkled into the feed. I read some unsubstantiated horror story about chicks eating grit only (ignoring their feed) and then dying, so I'm all paranoid about mine dying from "free choice" grit. I sprinkle it into their feed as if I were peppering my food, then I run my finger through it to hide it.
By the time they are 14-16 weeks, I know that the chickens I have here can tell feed from granite grit, so I no longer worry about them overeating it. I give it to them free choice and don't worry about it again. It will last in their gizzard at least 3 days, so I don't worry if they run out one day and I can't get it to them right that minute. They survive. (So far.)
I give it from about day 2 or 3. My chicks will sometimes tear up their paper towels and eat them. I put paper towels down and then transition to softwood shavings quickly once they figure out that they get feed from a feeder. Because I have seen them digging in the wood shavings and eating wood shavings, I feed the chicks granite grit because I don't know how their intestines will react to wood shavings. Because of eating wood shavings, I give granite. The same with grass and grass roots, etc.
Mouth, esophagus, crop, proventiculus, gizzard, intestines. That's approximately the route of chicken feed.
The grit is used by the gizzard to grind up their feed, as we all know. A whole piece of wheat could go straight through a chicken that doesn't have any grit in their gizzard. That is wasted food!!! Wasted money, too! The chicken got no nourishment out of it because it wasn't ground up in the gizzard. Even years ago when my chickens had grit, they couldn't grind up a certain type of millet nor whole flax. So I stopped feeding those grains to them. There's no point. So if my chickens get a mash or pelleted mash, if they are out foraging, which they are, and they eat a seed, I want that seed to be ground up in the gizzard and utilized.
That random seed has minerals that my chickens don't get from their chicken feed. I want them to get as varied a diet as they can get as inexpensively as possible. For that reason, I give them grit. That way I know what they eat is ground fully and that they are able to utilize all that they eat rather than having it go straight through them, plus they get some great and varied nutrients that make our eggs more nutritious and actually tastier than eggs from hens that have standard, non-varied feed. (Yes, we taste tested on our own chickens.) (But, you know, it's not like we'll always be able to free range them. Who knows what the future holds.) Plus they get kitchen scraps and they need grit to grind things like apple seeds, etc. No, not a lot of apple seeds, just a few now and then.
My hens get two feeders: One with whole wheat and oats or barley (hopefully no more than $15% on the oats and barley) and another feeder with a ground complete feed. They have our rocky naturally gravel driveway to peck at, but I still give them insoluable granite because it will last longer in the gizzard than some softer stones because they need some way to grind those whole grains. (It doesn't actually dilute their protein intake according to studies to have two feeders because the hens are (according to the university studies) able to differentiate between protein and carbohydrates and then eat the right amount of each so that they can lay eggs according to their genetic tendencies.) Works great so far ... we've got a 5 1/2 year old Black Copper Marans still laying great guns at 4-5 eggs a week. I'm really surprised by that.
Here's an article that basically says that it's beneficial for growing chicks and layers to receive granite grit:

I say what I happen to practice currently, but I think it's obvious that my way is not what I am suggesting as what anyone else should do. It just works
for me so far from what I can tell. There's more than one way to skin a cat; that's for sure. (Seriously, that is an odd expression. Where in the world did it come from?)
Hi there.. this is not in reply to your question (sorry!) so much as an additional one? I have 3 week old chicks in brooder... keep reading things about grit. What is grit? Do they need it? When I purchased them the lady didn't say anything about grit... am i missing something? Thanks and sorry I can't help with your question
See my reply above. Also, grit is tiny rocks ... usually granite because it's one of the hardest stones around and has a greater grinding capacity. The gizzard is a muscular organ where the granite grit will settle into, until the grit is ground away by rubbing against each other and the grains/grasses/twig bits/etc. The amount of grit in an
adult gizzard is about 1 teaspoonful, but, of course, it varies a lot from bird to bird.
I'm not sure ... but just because "the lady didn't say anything about it" doesn't necessarily mean anything, does it? I've never had any person (lady or gentleman) selling me chickens (or chicken feed ingredients) tell me that I needed grit. I think it's assumed that chicken owners will figure out what their chickens need or don't need. ::shrug:: To chicken people, it's just sort of common knowledge that grit is an option (or not optional depending on what you have read, heard, and witnessed concerning grit). I heard about it first from a lady in Scotland when she was showing me how to take care of chickens. So it's not just a thing in the US. It makes me wonder when folks started giving grit to chickens. I know that other seed-eating birds (song birds) also eat grit, so at some point people in the past figured out that chickens naturally ate rocks. I guess, for that reason alone (wild chickens eat rocks on their own wihout prompting from people), we should consider grit a necessity for penned birds.
I believe my chicks need grit based on reading and watching them eat shavings, grass, and other weird stuff. I also base that belief on seeing whole seeds in their droppings at times when I haven't been watching the level on the granite feeder. I also believe that they will grind all their feed more efficiently if they have some grit in their gizzards ... even if they are eating a mash alone. My opinion only. Many would disagree with me, though quite a few would agree.
