I have to say that the burm is more than likely not stunted for life. Its a burm man, they grow to a large size no matter what man. If they are fed less they will grow slower but they will get a large size over time. Make sure you have a breeder handy for rabbits and pigs(male or smaller female for food) and if its a female you'll need about 15-20 lbs of food every 2-3 weeks. About 10% of their body weight is a good sized meal. I know Rex who has Homer feeds him a 3-4 lb pig every 2 weeks and he is only a year old male!! You have a big responsibilty but if you have the help and support, go for it.
