Pig problems

[Z's Farm]

When I bought my pigs about a year ago I got a boar and three females. The runt of the litter is the biggest now. However the male is the third biggest and is afraid of the females even when they are in heat. We have him with the smallest female but she is super small and not aggressive towards him but we have not seen them mate. I have not seen her go into heat and she is constantly kind of fighting him off playfully. WHAT is WRONG WITH THEM. What can I do to get her weight up and can I make him mate with the other two or is it a lost clause. And I just need a new boar.

The female is on the left with the black spot the boar is the one with red eyes

This the second biggest Sassy

The two white pigs look badly malnourished. They also look like they could use a good worming. The others look better, but I'd worm them also. What are you feeding?

I feed them a mixture from my local feed store they are called porky pellets and half and half which is a mixture of pig and cow feed. I give them safe guard worm pellets every month or two sometimes less but even when I worm them they still stay pretty small.
