I am planning to add to my free ranging flock of 2 roosters, 1 goose, 3 ducks, & 5 hens. I will be adding a few full grown hens, 1 rooster, & 1 silkie rooster. (They will be comming at two diff. times, hens then roosters) If you have any advice as to how to introduce the newcomers... I would appriciate it.
