I ordered all females...5 Black Austrolorps, 5 Columbian Wyandottes, and 5 Buff Orpingtons. I did a bit of research and tried to get chickens that would be rather gentle and decent egg producers. I have two grandchildren, ages 7 and 4, so I want chickens that won't be aggressive toward them, and we want good, healthy eggs.
I think I would be happy keeping 2 of the black, 2 Wyandottes and probably 3 Orpingtons. Murray McMurray also throws in that "mystery rare breed," so I guess it depends on what that turns out to be, whether I keep that one, or not. (an Easter Egger would be cool!)
I'll definitely check out those links. I'd like to be able to sell them locally...don't really want the responsibility of mailing/shipping them...I'd feel absolutely horrible if any didn't make it to their new home! I wonder if I'd have any luck making a connection at the local County Fairs? Hmm....
You picked some good chickens for your purposes. Out of many, I never had an aggressive Australorp or Orpington (my children, and now my granddaughter, made pets out of them) and the Australorps are especially excellent layers. Good luck with your flock.
