I have 3 pullets that are 20 weeks old (Barred Rock, Production Red, and Ameraucana) and I love them. BUT I think Silkies are so pretty and I want one. If I got one in mid-late August at about 8-9 weeks, would I be better off getting 2 or one? I don't want one loner young one but 6 hens is my city limit so that would bring me to 4 for one but 5 for two. Please help me decide on # and how to integrate them into the older flock.
