I have a jack that is still uncut,Not sure about his age ,probably at lest 2 yrs,he is in the pastue with 2 phillies, one welsh pony, one QH ,both about 2 1/2 yrs, my question is i heard that when a donkey gets excited sexually they could be dangerous, should I be worried when I go to feed?I am most worried about my young grandkids 6 and 4 yrs, I dont let them in with the horses for fear of the Jack,Should I be so cautious?A ny advice on keeping a jack?The only reason we have him is he was given to us when we bought the welsh pony ,the man said they were raised together and thought the pony would act better if the jack was with her, my young grandson calls the jack his horse, should we try to talk him out of the Jack or can they be easily trained?
