In the end I settled for 3 permanent divisions as shown in the photo, Plot A being 2 Ha, Plot B is 2 Ha and Plot C is 1 Ha.
The most important part is I want to put in a handling pen and am going to put it in where I have the red star. I plan on putting in a road where the yellow line is so that you can walk the cows from plot B to the pen.
Has anyone else any better ideas on how to divide it up.
The red line is a main road and would be busy at times
The purple line is a side road and would have a few cars on it
The blue line is a lane and would be accessed by three main users
