Hello Folks- I am a new owner of a small flock of Delaware Pullets. They are about 12 weeks old. I had been keeping them in a large pen with ample space for them to run around, with a roost. I finished their coop last week and moved them into their new home. They've been eating and drinking well, but they show no desire to leave the coop. I leave the door open and they wont even go near it. They also will not use the roost, and sleep on the floor. Do any of you have any advice as to how I can get them to get out in the fresh air? I have a large fenced in yard and I wouldn't mind them roaming around it. I am planning on building them a run so they can be outside unsupervised. Is there anything I can do to help them get in the habit of using the roost? I tried placing them on it but they kind of hop off and then stay off. The roost has two levels, one about a foot off the ground and another about two feet (stepped with room for them). Any advice you could give me would be a big help!
