You can try posting some clear photos of the nether regions. It it’s always a good idea to learn to sex them. You are feeling for the presence/absence of the penis ridge above the slit (boar). Or looking for the presence/absence of the fleshy seal just inside the slit (sow). Have a read of the link below.

Where did you get them from?

Thank you, we have only ever had females and we think this one might be male after some research. We bought them from someone local to us.

Check inside the slit for a fleshy seal and feel for a penis ridge on the belly. Did you read the guide I linked above?
