Hay rack + foraging

So I've started using the hay rack and then putting hay on the bottom of my pigs cage so they can forage for food too. So far it's been making the mess a lot less. The hay rack idea came because I realized they wasted a lot of hay that they had wasn't being eaten because it was soiled or they just didn't want to, not sure what goes through their little pig brains. I do like both of the options because I do think that they're both different foraging options as well as saves time for cleaning and gives them options.
