My sow Custard has been in quarantine for a week now and has another week to go before she can go back with my other two piggies Cocoa and Chewy (also sows). She has an eye infection and can't be sleeping in the hay with the others, this has happened once before and it was a real mess trying to re-bond them so I thought I might get some tips. When we try getting them back together they always fight (mainly Cocoa and Custard, Chewy is a little sweetheart) so how do I stop this from happening?
