Hi , I have two female grass parakeets, unsure of age as they was given to me . Although the lady said they were a year old . They were ok for a couple of months and now one seems to be picking on the other one . I ignored this for a while and just kept watch and telling them to behave . But one morning blood was drawn . Since then they have been to separate cages either next to each other or near . Would I be able to put them together again or are they best left separate? I’d hate to think of them lonely but equally it was awful watching them chasing each other around the cage .
