here’s my story and i’m sticking to it! I have to admit I was full of trepidation. I was sure of issues occurring. 1 I moved the 4 weekers out to the coop but kept them within a dog cage kennel thing. On warm pretty days I put them in the run in an exterior broader run of their own. At all times look no touchy. I did this for a month. I then added obstacles to the run as well as hiding spots. Well,yesterday evening just before beddy by time I opened the teeny chicken door flaps I made in their exterior brooder in the run. They stepped in and out on their own. The 3 later roosting ladies totally ignored them. After the big girls were all roosting I put the babies into their night time interior brooder within the coop. This morning I simply opened their brooder door and let them out. The big girls could have cared less. I stayed and watched for an hour or so. Zero incidents !The babies even went to roost with the big girls! Life is good!
