Hi, I currently have 3 piggies housed separately, 1 male, 2 female. My little boar is having his op today so that we can hopefully get them all living happily together. He needs 6 weeks alone to prevent pregnancies but my question is do I introduce the girls together now and hopefully get them happily together before introducing my boar or should I wait and put all 3 together at once? I know this will have to be done gradually. TIA
