Do you know how to sex them properly? If not, get someone who does--it si possible yoiu might have a female. And it's NOT a gay thing. it's a domination thing. If they are both males--fighting will start soon. Males should have there own separate quarters.
lol...no such thing ad "gay" animals but they do tend to mount each other at times. I have a pen of all females and have seen it too. If you do have 2 males housed together you may want to seperate them though...males are aggressive & dominant where they will end up fighting each other and it could get ugly.
