hi people, ide like some help of some russian dwarf people around a month ago i purchased 3 male winter white dwarf hamsters, i found that one of them seemed to be deformed and he died 2 days after i had, had him. i have now noticed that another of the males doesnt seem "right". since ive had him he has only come out of his box twice to get food, (he is also coming for water but then rushes back into his box straight after) every time i handled him he continuously chatters his teeth as if he's scared ive been giving him mealworms to make sure he is gaining weight and also small amounts of seeds (sunflower & pumkins) but to me he just doesnt seem the same as the 3rd dwarf, which is really worrying me hes around 6-7 weeks old now (but this is an estimate) can someone please help !!!!!!
