User blog comment:Backwardy/Should I cull the herd?/@comment-5544049-20121108143207

Using your metric, I have 15 extra T3s... and I'm in the same boat. Fortunately, all of the habitats I have out hold at least three dinos, and as you said, coin isn't really an issue, so I'm hanging on to them for now. TinyCo may never do the crystals for dinos thing again, but with my luck, they'd do it right after I sold all my extra T3s.
