Can some "stones" be piled up at one side of the "tuppernest" to make a RAMP back in?
they'll walk the ramp and plop back in...then out, then in....frreeaakk me out!!!
...ramp those babies up....get in, get in, get in...chant!
I THINK they would be able to walk up a ramp, and I doubt "jumping back in" is at all possible...their body weight is too heavy for those kinds of aerobic/abilities.
