I agree. The bird should *always* have toys unless the toy presents a hazard, such as swinging around in a travel cage and bonking him on the head. (Fix travel cage toys to not swing, or put them in when you stop moving.) The bird will sleep (mostly) when the lights go out and wake, if undisturbed, in his own time. Why would you care if he doesn't sleep or wake by the clock - he's not a human child and he will never have learn to get up and go to work. On top of this, when he is not sleeping, having no toy just makes him have to entertain himself - a bird in a box alone has the choice of making noise, destroying whatever is available (a perch or himself), and developing stereotypic behaviour.
