hi and congrats!!!! chins are soo much fun!!!
are you sure he's not eating any pellets.. like they say a chin will eat about 2 tble spoons a day.. but not literally, but thats what i've always heard everyone go by.. as for eating alot of hay, that is okay.. my one big boy, loves hay... he would be out playing and if he saw my put hay in his cage, he would go back in to eat hay
but he also eats his pellets too.
so when you say he's not eating pellets do you mean NONE AT ALL, or just not alot... and do you see any wet spots on the cage, if you do, then he's drinking.
some days they don't drink alot some days they do.. at least that's how mine are.. i can't speak for all of them.. and of course on the day they don't i get all nervious, but the next day.. water is gone..
as for your girlfriend, chins take time to warm up to someone. so it might take her longer if she's not there much.
just curious, what kind of food are you feeding.. most of the pet store foods are no good for chins..
good foods are:
penpals, mazuri, manna pro, tradition.. just to name a few. i'm sure someone else can list the rest.. sorry but i always forget..
