So, I've been reading and reading about integration and I hope I'm doing things right. Currently our younger girls are three weeks and are in a brooder in the garage. Our older girls are 18-19 weeks and free range in a penned in area. I put a dog x pen with a cover on top and let the little ones out each day if the weather is nice. I'm planning on doing this for the next three weeks. By then we hope to have the walk in run completed and soon after the new hen house will arrive. We'll have to hen houses so the girls can choose either or. Now, when do I actually let them out together? Also, when do I let them in the walk in run without segregation? I know they'll use either house they choose after full integration but I am trying to figure out how I get from where I am and what I'm doing to the finish line of friends.
