I am new to this - and this is my first group of 9 week old little darlings (the chicks). They went outside 4 days ago for the first time, to their new coop. They have a 6x14, covered, safe run, and a coop that sits over part of the run. I put interesting things out there for them as well as their food & water, yet... they all end up running INSIDE the coop. The weather's been lovely... so I'm not sure what to do... Should I close the 'chicken door' and make them stay outside? Or do I let them go in / out if they want & feel secure? TO me... if it were my kids... I'd say "It's a nice day - GO OUTSIDE & PLAY!!!!" But... if they feel secure inside especially in this new stage - should I let them? They all come running out in the AM when I go & let them out. They eat & drink, and I helicopter forage as I'm working out in the yard & garden... and they love that... but... they're hanging out inside? I don't know if that's ok? Any ideas what I should do?
