So just to clarify;
You have 1 cage with Mama piggy and 2 daughters
You have 1 cage with a neutered male and another dominant pig?

My first question would be what sex is the dominant piggy?
And how long ago was the male pig neutered?

Please know that a male piggy can not be put with a female until 6 full weeks after his neutering procedure, so I am guessing you other dominant piggy is also male?

Or do you only have 1 male?
