I have 11 RIR and 7 plymouth rocks living in a 9x9 coup that used to be a shed. It's nice because the walls are solid, it's totally critter-proof, and I set it up so I've got about another 4 feet of expansion area if I need it. Couldn't figure out how to post a pic . Anyways, I'm trying to get them outdoors a little at a time now. They're right at about 8 weeks (I've heard you can start letting 'em loose around 2 to 2 1/2 months). I have plenty of space and my dog loves to stay with them without chasing them so I'm not worried about predators yet. The thing is, so far they just really seem freaked out by the outside world! I have to shoo them out and then they'll only peck around within about 5 feet of their home. I'm sure they'll grow into it but just wanted to hear any stories, etc. you guys might have about free-ranging. Another obstacle is the way in and out is a window about 3 feet off the ground. I've got little ramps on both sides with footing but figuring out the ramps actually lead outside and then back again is eluding them for now.
