umm i recently just modified my birds cage and added a nesting box to the side the next day i noticed my birds playing with the box like chewing at the hole and stuff. the day after that i noticed they go inside of it. I had some fluff in their box incase she lays eggs but they took it out will they mate? i live in northern hemisphere and its pretty much spring already my girl budgie and boy budgie are mature enough and when the girl is inside the box i guess the boy would come and share food with her you know when it appears they kiss. so i dont know if they’re going to mate are they?
