I would avoid the computer.
Something such as this can be done by hand with a ruler and pencil a lot faster than a computer will ever manage it (Usually in several dayd less time).
If you want a final computer output, scan the finished hand drawing.
If you REALLY want typed computer text, print it on a sheeet of paper, then cut and paste (Scissors and glue, of course) between documents, then scan or photocopy the "master sheet".
In fact, you can easily draw labelled boxes using something such as excel or word, then cut those out and glue labelled "stalls" on a plan of the field. This is known as "Hybrid technology".
Quack!
