This is not related to pig feed, but we had 8 tonnes of sheep feed bulk blown into our granary from BOCM Pauls, it was just dust (meant to be nuts), they were very helpful, sent two guys to shovel it all back out into the wagon, new delivery, just the same, MUCH less helpful and it all got quite difficult. Was resolved in the end as the feed was clearly faulty, but was quite stressful.
