I don't think a T60 is a good choice for BPs. I guess your thinking of putting multiple dividers into the single cage? The dividers work best 1 per cage as they will intersect with the center support. Dividers not centered will leave a small gap between sections. I think a T3 is great for adults and you could divide it for the youngsters. A T12 is wasted space for BPs, they don't need and won't use the height. A T8 has the same floor space and is half the price. You'd be much better off getting 3 T3 or T8 for about the same price as a T60.
