Hi! So I just got 3 baby chicks last week and I've never had chickens before... They're only a week old but I was wondering if I could take them out in the grass in like a little pen to just play for a few minutes when it's warm out? Supervised, of course. Or do I need to feed them grit in case they try to eat the grass or something, and how old are they suppose to be before they eat any kind of grit...? Haha sorry if some of these questions are stupid, I just don't know what they would do or anything, and when in look some of this stuff up i get different answers. Or can they just not be outside at all until they're a little older? Thank you!
