Pig Auto Drafter

[chickens and wheat]

I remember weighing or trying to weigh pigs as a student, the holding area had vertical bars as a fence, the pigs all stuck their snouts between the bars and refused to move, chaos
We had some pig boards but as 'student' all i got was an old piece of corrugated roof sheet.

My next placement had similar but with solid fences and proper boards, relaxed staff = easy pigs
