I have 5 young chickens...probably hens. They were hatched the end of March and early April this year. After a tragic loss, I acquired another a month later. I want to introduce the newest member into our big run soon. Today, this newest spent a few hours in an enclosed pen within the main run. There was a lot curiosity by some, others could care less. Since the older chickens are relatively young, I want to know if there are special or unique things to consider in getting them to co-habitate. Do I follow the same protocol? I am worried since I have read about the difficulties of introducing a single newbe. We also have three ducks. Thanks for your help everyone!
