Thank you for getting back to me. I'll try to keep it as brief as possible, although I may not be able to! I have a herd of one neutered male with six ladies. Two weeks ago I adopted two adult males (brothers who've always been together) I kept the two new boys in the sitting room for a few days until they got used to new sounds, smells etc. Last week I put them into 'the pig room' in a separate cage, & all hell has broken loose! The new boys have started fighting to the point of blood shed (I've separated them, but one is in a small shop cage) & my herd have started grooming each other (they are or were long haired) I'm at my wits end 7 my heart is breaking for all of my piggies! Sorry, this is a long message. I hope you can understand my upset? I'll be very grateful for any advice. Thank you.
