We already have a rooster, he is top of the pecking order and has 8 hens. We have a hen sitting on 8 eggs that are due to hatch in 5 days. We are planning on keeping all hens that hatch to increase flock size and are also thinking of keeping one of the probably many cockerels that hatch. The current rooster is very small and slender so we were wondering if the size of the rooster we choose to keep will influence them fighting often or not? (two roosters the same size is a fight worth fighting) or (If one is a lot bigger it will bully the smaller) or should we just pick the one that seems the most laid back. Any advice would be great.
