I'm considering what breeds to add to my flock this year, and am deciding between these three breeds. I think yokohamas are beautiful birds, but how are they temperment wise? Are they very hardy? Cubalayas are interesting. How are their temperments? And are they cold weather hardy? I know they do well in hot humid temps but how about the cold? And Malays. Are they aggressive with other birds? Anybody had any? Hardy or not? Easy to raise or not? Opinions please!
