Thanks everyone.
Sarah you were spot on correct about the chestnut agouti but the other two are not otters sadly. i was getting over excited thinking i got an otter. but they are both actually self blacks.
i dont have any photos at the moment as my father and brother are taking care of them at the moment but i saw a video of them trying to chew at the hay and it was the cutest thing in the world and they were hopping around although the runt looks to be a bit of a clutz but that was last week. i will have to update on photos and what not when i get back in 10 days. they are going to be so much bigger than my last update haha
