Hi there, I have 2 boars One choc and white smooth coat and one red and white long haired coronet. I believe they are both the same age about 3-4 months old i dont think they are brothers but I got them from a petstore rescue area :{someone had too many babys and were trying to get rid of them on the cheap! anyway.. they were both pretty much the same size when I got them and in fact the long haired boy Reilly seems to be bigger than Nummies due to his fluffy long hair.. but in the last month Nummies has gotton HUGE! I know they are defn both boars so I know it not due to breeding ! It doesn't seem to bother Reilly who is definately the boss of them both, Nummies follows him round like a puppy nose to tail so much that Reilly does get ' annoyed' occasionally needing his own space and will ban Nummies from coming in the 'bedroom'. Has Nummies just had a growth spurt?.. His back end is a lovely and fat little rump but Reilly is just all hair and I can feel his back end bones quite alote.. he eats the same from what I can see if anything he eats more as he is so bossy . nothing out of the ordinary poo wise.. etc etc . Could it be that they are just Different!
