My flock outside are 4 month old BRs that I just got a few days ago. I've been reading up like crazy, but couldn't quite find my questions. My chickens have been spending all their time in the coop. I want to free range but I'm leaving them in their coop for a week to get used to it. I open the door to the run every day and they MIGHT go out for 5 seconds and go back in. It's been a bit cold and rainy lately but today is beautiful, sunny and 18 degrees. I've shoo'd them out, but they wander back in. I even put some treats in the run to entice them out. When I check on them in the coop they're huddled together like I'm freezing them or something...instead of out in the warm sun. Is this normal? They're also huddled on the ground and not using the perch or roost in there. Are there tips to getting them used to the run? I have no idea of their background, by the way, or how they were raised.
