Get a routine - they'll soon learn it. Mine went nuts as soon as I got up and I was giving veg titbits constantly to keep them quiet so they didn't wake the house. So they squeaked whenever they heard me move! Then I read a forum tip about a handful of fresh hay for enthusiastic wheekers and
it worked.
Now it's:
Get up - 1 piece veg each - then
one big handful fresh hay always in the same place so they all come out and munch together.
Someone fetches grass in a bag (usually between 8 and 10 am, depending on the day) - pigs know it's coming and lie silently in wait out in the open, like in that Alfred Hitchcock film 'The Birds'! (I
must get a photo of this)
Grass arrives - bag rustle - pigs go mental - serious face-stuffing - retreat to hideys and collapse to sleep it off and don't emerge until after lunch.
Few hours outside if nice weather - bopping round inside if not.
Dinner prep for humans - more veg for piggies as they hear me chopping and just assume it's for them anyway. They've even learnt to stop squeaking if they hear me say "for goodness sake, it's an onion - it's an ONION!"
Cage-clean and more hay/pellets.
I don't give veggies in a bowl as there are 4 pigs (two pairs) so I hand-feed to make sure everybody gets the same. My older boar's bowel does
not react well to a lot of veg! They know what's happening now and don't snatch from each other any more - they all know they'll get one but each runs off to a hiding place to eat undisturbed. Lovely Louise is now so trusting that when she occasionally drops her morning lump of pepper as she dashes back into her bedroom she leaves it there, reaches the hidey and then pokes her head out, waiting for me to pass it in to her!
