ondrh: Hi. Whatever I do, I cannot supply my mills - bakeries/pig farms. So, my question is: How to place Grain Farms efectively to make them produce enough wheat for my food producers? Or is there any other problem?
Make sure there is enough empty space where the farmers grow the seeds. It has to be green and preferably level (green or yellow dots will do). You can change working location just like you'd do for other buildings by selecting the farm and click change working area, or by right clicking on the desired location.
Also, do you have enough of them? I usually had 1 far supplying 1 (mill OR pig farm OR brewery).
