We got 9 chicks at 5.5 weeks and now they are 6.5 weeks and I take them out in a big dog crate without a floor when it's nice outside to nibble grass. They live inside the house and the place I got them from said to keep them living inside for another 3 weeks at least. Because they live inside they don't call the coop home at night and it won't be up for another few days anyways. My question is when I can I let them roam in the 4 foot fenced in yard freely (supervised) and be able to round them up again? Any tips for a the first few times? Should I wait til they call the coop home? Even if then, at what age do you allow chicks out freely with supervision? I'm picturing 9 chicks flying over the fence in opposite directions..... Thanks!
