If I could do only four, - I'd do an
Araucana, a
Marans, a
Polish or
Houdan, and a
Shamo.
I'd get all of them only from a breeder, a good one. Shamos aren't for everyone but there are some people I'd recommend, one who sadly doesn't do Shamos anymore though. As for Araucanas I always recommend Ann Charles or Gary Ramey. Both ship chicks and eggs. For Marans I'd probably go to Wynette, hatch some eggs, choose a nice girl, and sell the rest since I could only have so much in this scenario. For the Polish or Houdan, the Houdan I'd get from a specific member here on BYC, again get eggs, for the Polish I'd probably look for a Tolbunt breeder with stronger lines than most. Again eggs. Towns may have ordinances but no-one can really jail you for having excess chicks for a couple weeks.
The Araucana is for blue eggs, longevity, and cool appearance.
The Marans is for a large calm bird with seriously dark eggs.
The Polish or Houdan is for a beautiful super friendly bird with white eggs.
The Shamo is for a seriously cool and rare bird with amazing nobility longevity and friendliness but with typical light brown eggs.
