My flock has grown to 12, I picked up 5 chicks this spring from another chicken lover. Her flock is very divers and these where of unknown parentage. 3 are obviously at least part Brahma and they turned out to be roosters. They beautiful boys and have found a place in our hearts. They are now about 7 months old and so far have gotten along with only one known argument that was surprisingly less violent then expected. I do have a plan to double the size of the pen to 15x35, as I am sure the flock will grow again. My plan also is to increase there access to free range space and time. Since the boys have been together from hatch would this be enough to prevent fights? This is very much like the set up they came from, tho she had a larger flock. I do plan on adding more hens, most likely in the spring. My long range goal is to have a broody hen and use her to replenish the flock. I might be over thinking this but would rather have more info then less. I am still rather new to keeping chickens and how they behave.
