Of the four hens and 1 rooster I have in my mixed flock they all have a great temperament. My rooster at 20 weeks is already alerting to danger and caring for the flock. He is not aggressive either like some of my other roosters of the same age. Then hens are very well tempered and are able to handle my mixed flock that contains hens that range in age from 3 years to 20 weeks. They love people so be prepared for hens that will run to you for attention. Eggs in my older Welsummers are beautiful in color ranging from mid brown with spots to light brown with spots. The are a breed that will always remain in my mixed flock.
