Thanks for everyone's advice. I looked in the classifieds on this site and came across an ad from a member from CT who is reducing her flock. She doesn't want to part with them because they are her pets, so I know they've been well cared for. I'm getting six hens: 2 black stars, 1 white rock, 1 silver laced wyandotte, a red leghorn and buff minorca .
These are 10-month-olds so I am going to have to be careful, and keep them separated for a while when I introduce them to my single adult bird for sure. I'm new to this, but I can see what can happen a mile away. Then again, it'll be six against one!
Thanks for the advice everyone, and all the welcomes. We'll see how long it takes before I get the itch to build another coop, or convert the entire shed to a coop, instead of the room I made inside it! I can see this being very addicting.
