I showed my Black Australorp....sweet as can be, did great in the show(champion english, Res. Champion Large Fowl, Best Australorp) , and is a great layer!!! I don't know if they are very exoctic though.....blue laced red wyandottes are a different color and are soo sweet and they aren't recognized by the American Poultry Assoctiation but you can sometimes still show them. Or you could even go with Americuanas, they lay green or blue eggs and have fluffy beards and tuffs and come in a variety of colors, I'm sure they would do good in shows too. Another great exoctic breed would be a sicilian buttercup, they lay well, and are just gorgeous and are very unique. I probably didn't narrow down the list of hundreds of chicken breeds because i just told you about 4 awesome breeds and there are plenty more awesome ones out there
