Pigsitting Hay bits amd vacation time

[Magicrebel]

Hey y'all new to The Forum, but not new to piggies. I will be going on vacation next month for about a week and can only have somebody stop in twice... I tripled water bottles for everybody and planning on throwing in a gooooooood bit of hay. Like an extra three or four handfuls... But I have a feeling that they will still go through it fairly quickly.... My question is the leftover dust at the bottom of our bags of Timothy Hay... Is there a way I can compress that that and make cubes that may last a bit longer for them until my friend can stop in?
