Why won't my budgies enter their nest box?

i think they probably just dont want too right now. i dont think they are distracted by the toys, if they want to breed, their instincts will take over. besides, they need some sort of "distraction" seeing as how they are captive birds who dont have overly much to do (not that im saying that you are at fault here, but captive birds dont have to be foraging, flying etc all day so they need something to do, like play with toys). it doesnt sound to me like you are doing anything wrong :)
