Sorry! LOL Today my husband and I put the run together behind the barn and will be blocking the gaps so the birdies can play outside tomorrow for a few hours in the sunshine, I hope. They are (counting fingers...) 18 days old today. How long do they need to play in the run (nice and big... for NOW) before they can be taught how to free range? One week? Two? Until they start looking crowded (which will be a while, since I'm processing half at 4 or 5 weeks old). The run, in case it matters, is a half circle around the barn, made up of eight 6' panels and one 2 or 3' panel. It's pretty big and has lots of low brush and saplings to play around and under, but plenty of bare-ish ground for digging in, too. Edit: Seven 6' panels, not eight.
