I have to chime in on this one. We were like you, very undecieded, and really wanted to make the right choice. After reading everything we could get our hands on about all the breeds, we had it narrowed it down to two: Wyandottes or Buff Orpingtons. (Both Standards)
So, we got both! We have 4 BO's, and 4 SLW's. We threw in 1 SLW Rooster, and we have the best ever little flock!
I have to say I am quite partial to my BO hens, they are the BEST. Talk about loveable, and friendly....wow, they're the best ever. I adore them. They are laying beautiful brown eggs every day, and our temperatures are in the -0's. We had -17 this morning, and I had 4 beautiful eggs. NOT to forget my "Andy" girls, they are laying right thru the cold as well. And they too are docile. And our SLW Roo is a nice gentleman, keeping watch over "his" flock.
It's a perfect little group. There is not a thing I would change or do differently.
