Help with CD4013 chip...is this fried?

I have a couple of CD4013s that I'm using to flip flop the logic signal for RG Keen's simple remote relay switching project. One of them is working like a charm (both sides), and the other is not (again, on both sides). I've checked the connections, and they seem to be hooked up correctly, receiving correct voltage, etc.

Voltage is reading 11.78v
On the chip that's not working, Q1 is always at 6.4v, -Q1 at full 11.78v
On the second channel, it's the same problem reversed, Q2 at 11.78, -Q2 at 6.4

The clock signal is clean and at full voltage, according to my dmm. What gives? Is it possible, it's just a bum chip? RG? Are you out there?

Thanks to all. If I ever get this project up and running, I will post build (war)  story.

Just to clarify and preempt the obvious question, voltages remain constant on all Q's when triggered by clock input.
