Hello, I'm new on here looking for advice, I have two jack donkeys who will be getting gelded in the next few weeks who I found abandoned last year (common where I'm from) they are roughy two years old, they have always got along fine but for the past year but last night one of them suddenly got very agressive tweeds the other one chasing him and biting him, I got up this morning and the one being attacked hardly had the energy to stand so I've split them up because I'm unsure what else to do. Why would one donkey suddenly get so agressive and wild? They have been apart all day and the agressive one keep walking along the fence and making vocalisations while the victim has just been eating and sleeping as normal not agressive at all. When the get gelded might they be able to be together again? I don't have enough room to keep them apart for good
