My piggies are about 65 lbs now... I have 2 white ones, 1 boy(well was a boy) and 1 girl. When asked which was which I looked under and figured it out. Well now the girl looks exactly like the boy underneath. She had a protusion maybe golf ball sized in the same location as boy parts(yes I am sure it is not a boy). I felt it and the mass itself is like a half a golf ball and firm/hard to the touch. Is this a rupture? Will it hurt anything? Other than that the pig seems to be eating and playing and growing.
