I'm going to try rainbow swing chard, but I'm almost embarrassed to say why. :hide I hate the taste, but it's super pretty and i figure the chickens can eat it.
I'm in Maine and I keep mine in the chicken run. It's along the back fence and gets Sun for about 8 hours. It has trees sort of hanging over it which keeps it from drying out. If it seems dry I just wet it down a bit while I'm filling caterers.
