Yeah I realized after I finished it all that I forgot about the waiting about a week thingThe only time I have ever fed two was when the place I normally get my mice from were out of the larger size I normally get so in a pinch I just fed him two smaller sized ones until they could get more in. I have read a few places about them feeding their Balls two mice to get them to bulk up faster but that isn't really necessary in this case so I would just go with one. So wait about a week and try again, don't worry they can go quiet a long time without food and often go on hunger strikes so another week won't hurt. Try and pick a day that with be convenient for you most of the time then feed him that day everytime around the same time. It will work best for you both that way. Like for example I feel mine on Fridays at around 3:00. This isn't super necessary but it does help him get used to a good feeding schedule and it will help you never to miss a feeding. Sorry if these seems irrelent or like common knowlage, I remembered that particular face helped me a lot when I first started out.
I hope this all has helped you
