Someone local to me is selling silver phoenix and red shouldered yokohamas. They are adults. I'm so tempted but I have 11 6 week olds out in the coop now that are getting along beautifully, 8 partridge silkies that are 3 weeks old today in the brooder. When I bring the silkies outside to join in the fun there has been no issue. i'm nervous about introducing a couple of adult hens (or a hen and a roo) into this situation. I've had great luck raising these babies, and mine are all very loving and docile having been handled daily by myself and my 6 kids.
I know you have a lot of baby chicks anne, have you introduced adults into the flock before? If so, how did it go?
