So we have 2 Barred Rock hens who are very happy that we moved to the country as they now have almost 4 acres to roam about. Unfortunately for them, they're utopia is about to be disturbed by three more hens and one rooster. They will be 6 weeks old on Friday and as much as my husband likes having hot chicks in his garage, they're getting too big and smelly for the brooder. With our first bunch we put them outside at 6 weeks but now we have the issue of introducing them to the other hens as well as it going to be mighty cold here very soon. From what I've read, 6 weeks is entirely too young to introduce them? Should I just set up some sort of brooder situation in the barn with our other girls but kept seperate? We have the other hens just loose in the barn at night because we haven't gotten to setting up a specific chicken area.
