I've been using haybox for years, we get the timothy blend. Like all hay, batches can be different, so sometimes it is more of the softer cut and sometimes more of the courser cut. Subscription is excellent, when I run out of hay early it is super easy to change the date and it comes within 3 working days most of the time. The only thing that annoys me is that the boxes are more often than not damaged, they said this is an issue with DPD and are trying to rectify it - but I am still having issues 6 months later with damaged boxes arriving.
If your pigs prefer meadow hay, I would recommend hayday - it's a lot greener than the haybox meadow.
