We have 9 outdoor free ranging chickens. They have been roosting in the trees following the dutch Bantam hen who is the alpha hen. A week ago, we finished building our coop and run, and had to teach them all how to go 'home'. First we called them to the run with food. They always came when I made a sound, "cuckoo cuckoo". They know it is their call to food. So I lured them into the enclosed run, and made sure all were in there in the evening time and I locked them in the run and the attached chicken coop for 3 days and nights. During these 3 days and nights, we made sure they had plenty to eat, had lots of luxuries to keep occupied and we made sure they went into the coop to roost. The first night, the husband had to handle a few of the chickens and throw them into the coop, then they just went up the perches naturally. After that, it became automatic.
On the 4th morning, I let them all out to free range as per before. In the evening time, again, I would call them to the run with my sound. They came and same thing, we locked them in. The wilder dutch bantam hen and her son refused to go into the run, I think they were so used to sleeping in the tree, but I 'herded' them into the run while mum kept feeding them cereals. Once they were all in, same thing, we shut them in till the morning time. Now this is regular behavior and they are getting used to the routine of getting out to free range in the morning, and then going home at dusk. They love their coop and run so much, they even voluntarily go into the run during the daytime to chill and hang out. Only the dutch bantam hen is laying, so her nest box is also in the run.
We have 10 Polish growers and 7 Cochin bantams that we plan to put out soon. We will introduce them to the outdoors first slowly, moving the brooder to the porch for a few minutes each day and then lengthening that period. Once they reach adult size and have all their adult feathers, we will move them into the enclosed run, and keep them in there for a few days and nights so they learn where is their home. Then after a few days, they can free range like the adults do.
A step by step process may work better since the chickens need to learn everything. Including where the pop door is, how to go up a ramp to their coop, how to climb a ramp to perch, how to perch on a roost etc.
