I have 11 chicks in my regular coop in a partitioned off "nursery" area.
I started with 5 4wk chicks, at 5wks old I moved the edge of the dividing fence to allow the chicks into the main section of the coop but keep the adults out of the nursery area. On the first day of full access to the regular coop area, the chicks all ended up out in the run with the adults. They spent the day out there, if they got near an adult they got pecked but if they stayed away from the adults they were left alone. They found the food and water and kept to themselves the rest of the day. At dark I had to manually pick them up and put them back in the coop.
I got an offer for 6 more chicks(maybe a week younger than my existing 5 chicks) the day after opening the nursery to the main area. So I reclosed the main area access and added the new chicks. The mixing of the two batches of chicks went well and there were no major problems with the integration.
A few days after introducing the new chicks I re-opened the access to the adult section of the coop. All the chicks now come and go between the "nursery" section and the adult section of the coop, some even roost at night in the adult section.
Now the problem: The chicks won't come out of the coop into the run on their own. I see them all day long peeking out of the pop door, some come out onto the top of the ramp for a moment or two or I can coax them out onto the ramp with treats but as soon as they finish the treats they return to the coop. This past weekend I let the adults out to free range before trying to coax the chicks out, thinking that maybe they were too afraid of the adults. I coaxed them out with the treats but they still wanted no part of the run, eat the treats and return to the coop.
So should I force them out into the run and monitor the flock to make sure they are not abused by the adults or should I just leave them to their own schedule and let them find their own way out when they feel like it?
