Here's what I did with the hardware cloth, not a great picture but it gives you an idea:
See the guy in the upper right hand corner? I made like a little cage with the hardware cloth to keep the chicks separate...this is a trial run, I don't really care about these chicks mixing but I will care with my call ducks once I have them separated. Hint: wear some kind of gloves when messing with that hardware cloth.
