introducing 3 adult females

[Angela Dimella]

Since I was told not to put my 27 month female with her 2 27 month old
brothers, is it possible to put her with her sister and her mother? She
didn't get along before when I tried a one on one intro of her with one
of them. SHe is now seperated from them and the mother and sister are
together. Is it possible to introduce her to the two of them again? I do
not want another gerbil, as I have 5 now, but don't want her alone since
she seems lost. Any ideas?
