I think putting a chick in a coop at dusk isn't that tall of an order. I would definitely ask her to check.
It sounds like it is just that one chick that is still having a hard time. I would like to think their survival instincts would kick in, and they would find their way into the coop eventually, but having someone check at dusk would be more ideal for sure.
I think that she will jump out of the play yard as long as she is able to. Birds don't always think clearly about that kind of stuff. Is the MHP a heater? I was thinking that might solve the problem to have a heater they can go under if they are cold. Maybe you could just put a chick heater at the bottom of the ramp in case the yellow baby doesn't figure it out.
