I believe my button is broody. She has been sitting on an egg in her nest that is in a small box. She has been in there all day and has only come out a few times. She does this warning? chirp when she comes out and stands in a defensive? posture when she does come out. Her mate seems a bit puzzled by the whole thing. If he gets to close she chased him away and pecks at him. She only has one egg in there. There tank is messy right now and I was supposed to clean it tonight but I don't want to stress her out. What to do? As much as it would be neat to have her hatch some, right now I don't have the room for more. How do I break her or can I just give her some marbles?
