Switch Pigs not producing truffles

[SP2186]

I don't know theirs some invisible limit of how many truffles can be produced a day but with two deluxe barns all full of pigs I only make about five truffles. Maybe their too close to crops but any help would be appreciated.

Pigs do need a clear area to produce truffles, so you may need more squares that are empty. If you can attach a screenshot that would help!

This may not be the best example, but now it seems like their producing truffles. Do you think I should give them more room?

That looks like enough space, are all your pigs happy when you pet them and do they have full hearts? If they have a lower friendship, they have a lower chance of digging up truffles. Petting them each day and planting grass can help if that's the issue.
