Yes, 16 seeds planted and watered, but after that? A friend of my son's who likes to try to break things told me about his latest finding, and so I downloaded CJB's Item Spawner to verify. Sure enough, that's evidently not a sufficient condition. On my standard hardcore farming start (63 seeds planted and watered), usually, that means 0-2 crows per day. I've occasionally lost 5 crops before the scarecrow. But spawning in seeds, never leaving farm nor accepting initial parsnips, it looks like you only ever get 1 crow max, about once per week. At least up until Winter, two runs, one with mixed seeds, one with a sort of randomly chosen seasonal crop resulted in no more than 1 crow, even planting up to 126 seeds (14 sets of 3x3, to keep watering easy, and not run out of energy.) Either I've had insane luck or there's some condition other than total seeds growing required to unlock the later crows. Any ideas?
