I have 2 adult females and 1 adult male housed together currently.
I need to know how to introduce this new female (YES she has been quarantined) without the male ripping her to shreds. Last time I tried introducing her, a huge fight broke out and she ended up getting a very bad wound on her back. The male then tried to attack the female that he has been housed with and has mated with. All of this happened because I tried to put her in the same cage as him. What can I do?
Thanks.
