I think anyone who raises chickens is familiar with the point at which the baby chicks outgrow their welcome in the house. We reached that point several days ago, so what a pleasure to get this little pen set up & move these guys outside, then vacuum up every last wood chip from the den! The white ones are my 2.5 wk old Trader Joe's specials! I had some wire shelving I got from my neighbors when they moved -- works great to cover the top! I'll bring them inside in a little wire cage at night for another week or two, then maybe I'll have some coop space freed up for them!
