Lovebird care and cage?

I have 2 love birds and they came with a nesting box. Im not sure what their sexes are but they sleep in their box and no where else they love it! And 1 thing you have to have if you can get your hands on it!!! is willow branches they absolutely LOVE them!! My loves are great they sing and sing constantly. They are bonded to eachother though so they accept us as a part of their flock but we cant touch them or anything like that but they do come out of the cage and go back in just fine when play time is done. Considering that my lovies are wonderful for me and they dont even like me lol I think you will have a great time with yours. 1 lovie is very easy to bond with its when you have to that they bond 2 eachother and not you. Good luck!!
