Too bad about your late summer planting. You have plenty of time for other fall and winter crops. You can't go wrong with peas, because you can eat the pea shoots no matter what! Same for turnips with the turnip greens. Mustard, kale, spinach, lettuce, broccoli raab, pak choi, swiss chard, miner's lettuce. There's still time for anything you will harvest as winter greens. The cooler weather may be just what they need to do well. Enjoy all your new chicks!
