Rescue piggy has bad behaviour

Question
I got a baby about a week ago from a woman who had many many pigs but wouldn't let me in to see how they lived. She brought six males out that were piled into a "show" cage less that 12" by 12". They seemed perfectly fine all piled together like that which seemed odd to me. I held all of them and most were very fat/healthy and BIG. All were absoulutely filthy. Everything stunk terribly. I finally chose my pig, the youngest one as I am trying to build a family of boars and they seem to deal better when you add babies. I immediately bathed him as he had gunk all stuck on his feet and he smelled horrible. His fur was stiff. He still smelled after his bath but it eventually wore off.

My question is this. My other pigs seem to have no problem peeing in their toilet which is a large plastic bin 1' x 4' and filled with carefresh. I also feed them their hay and pellets in there and the water bottle is also in there. I keep finding this new guy laying in one of the beds where he has peed and is just laying in it.

I think he is so used to not having his cage or himself cleaned that he's lost the natural instinct to stay clean. I've separated a portion of their home so that he only has a small area with bed, food/water and a small litter box and as long as he is there he keeps that space clean. It's almost as if he has so much space in their home that he can pee anywhere and still have space to lay, except for the fact that I catch him laying in it.

I thought he would learn from the other pigs but so far he hasn't. I don't know what to think.

Oh, she also only fed them pellets and I can't get him to eat hay at all. He is starting to nibble on the left over veggies when the others are done so thats a good sign.

I'm guessing he is about 5 weeks old.

Thank you so much for any help you can give me.

Hi
this poor little lad has had such a horrible start in life and may never be as clean as your other piggies.
He will eventually learn that you are someone he can love and may follow what the others do - its no uncommon for piggies to lay in their own pee anyway.
Can you get him to eat grass? If so then he will learn to eat hay. He is more than likely nibbling it when no-one is looking and he will definately start troffing when he gets accustomed to the routime of the others.
As for the witch selling them, is there any way you can report her for overcrowding?
Please let me know how this little one goes on.
Hugs
