  This work examines the confining-deconfining phase transition in a hidden
Yang Mills sector with scale $\Lambda \sim 10^{14}$ GeV appropriate to dilaton
stabilization and SUSY-breaking via formation of a gaugino consensate. If the
transition is assumed to take place through homogenous nucleation, then under
reasonable assumptions it is found that a critical bubble, formed at a
temperature which provides enough supercooling, is not large enough to
accommodate an adequate number $(\gsim 100)$ of quanta of the confined phase
(`hidden hadrons') to allow a consistent thermodynamic description. Thus, a
first order transition in the hidden sector may not be possible in the
expanding universe.
