First of all, I apologize for my English. I bought a 1-month-old female guinea pig that was recently separated from its mother so that my 3-month-old male guinea pig would not be left alone from a breeder (not from a petshop). But it was very weak and small compared to my 3-month-old male guinea pig(YOU CAN SEE MALE(3 MONTH) AND FEMALE(1 MONTH) GUINEPIG DIFFERENCE IN PHOTO)/I THINK DIFFERENCE IS SO MUCH. IT seems to have 2 wounds on its head and butt (.I'm not sure if there is a wound or not) Is the reason for the thinning of hair on its body due to the breed of the guinea pig(Abyssinian?) or due to a lack of vitamins/nutrition problems? There is no problem with it eating grass and pellets right now, she is very active. Is there anyone who can help ? I also added the photos
