Is it sentimental? Based on appearance, personality? Egg color? Do your breed favorites change from year to year? My favorite breed is a Buff Orp. They are fat and mom-ish, they remind me of an Italian mother who always wants you to eat more. They also have a laid-back temperment (in my experience). Lots of nice eggs too. My favorite individual hen is Betty, a white Rock. She hatched out 4 chicks this past year and is such a good mom. All her chicks have grown up to be such smart chickens. She alerts everyone when danger is near and ensures that all her chicks, even full grown now, get their fare share of food when it is thrown down. I will cry like a baby if anything ever happened to Betty. My sons and I decided that she would deserve some kind of eulogy/funeral and not the standard burial (throw carcass way out in the woods). How bout you?
