I have two Red Stars that are about a year old now. They are great girls and are out free ranging in the yard on most days. They usually both roost together at night on their perch which is about 25-39 inches long, but this week one girl has started sleeping in the nesting box and so there is poop in the hay too. I have also notice some feathers in the bottom of the coop. They both seem to get along well and I have never noticed any bullying between the two. Any thoughts?
