OEGBs, Easter Egger mutts, and Production reds.
OEGBs are just adorable little mothers and they go for a lot at auction without eating much. The good roosters are awesome gentlemen. Also, autosexing chicks.
Easter Egger mutts (Wyandotte, Silkie, Australorp crosses) make up the backbone of my flock and go broody often. I happen to like this trait, and the fact that they make great mothers. Their multicolored selves are interesting and all of them look unique. Their green or pink or weirdly grey eggs make a very nice addition when I'm trying to pay for feed by selling eggs. And their combs don't freeze in winter.
Production Reds (And I know I'm going to catch flak for this, but I like them) have a ton of personality, are good producers, and sadly, my oldest hen (Peahen) just started laying lash eggs, so I'm feeling sentimental.
Give a reason why, too.
