I have 4 hens living in a 8 x 8 raised coop. Due to the small size of the coop I am considering building a small makeshift coop in my run (8 x 40). My idea is to house the established hen in the temporary coop in the run while the chicks grow. Run is well built and bird netting on the top. Have never had an issue with predators, but maybe that's because the hens are secure in the main coop. When the chicks grow to hen size I will introduce and everyone lives back in the coop. What are your thoughts about my plan?
