I don't think you can go wrong with Plymouth rocks or Rhode Island or New Hampshire Reds or Orpingtons if you want an attractive yet productive flock. And even though they aren't exotic, IMHO there are few breeds that are as pretty as Red Island Reds. For pure enjoyment, Cochins. Although if you want setters and mothers, they too have a practical side. I am partial to blue breeds/varieties too. Egg color doesn't matter to me but if you have kids or grandkids who want to die Easter eggs, then you need a white egg laying breed, Andalusians, maybe. As I said, I like the blue color. I love the Polish too, but they may not do well in a mixed flock with more aggressive breeds because they might get their crests pulled. I've had that happen. I have mixed feelings about the sex-linked hybrids, many times they are bred for commercial production and burn out after two years. I guess that depends on the breeding program. I am intrigued with Bielefelders but don't know how well they'd do in our humid south climate.
