It's a nice day, and I'm contemplating letting my six 7-week-old birds out for the first time. I'm kind of afraid that they won't return to their little coop and be impossible to catch. I also have five older pullets (4 of which are laying). Would it be a Bad Idea to let them all out in the yard together? There are plenty of places to run and hide, but I'm wondering if the little ones might just continue on over the fence... WWYD?
