Advice?

I just bought 3 Chinchillas, advertised as 2 females and 1 male. The 2 females are 6 years old and 3 years old (apparently). Male is apparently 1 years old. The 6 year old is very blind, both eyes are completely filmed over with a milky look and the other looks like she has a moon in her eyes? It’s only covering half, but she seems to see more than the other.
Should I take the male out? I don’t want them pregnant considering their obvious health concerns/issues?
