Greetings! This is a wonderful site, I've learned a ton already! We have 6 NH Red chicks about 3 weeks old. They seemed hugely interested in getting outside each time opened the coop so I let them out in a small pen in the yard yesterday. Is this OK at 3 weeks? I was told at least 6, with their feathers. Once they've learned where their food is, is it OK to put shavings in the coop? We've been using newspaper so far. Should I only be giving them chicken feed at this point? When is it OK to offer scraps? Many thanks to anyone with advice...we're very excited to have joined the world of chicken enthusiasts!
