Just google 'BCD truth table' and you'll find several.where can I find a truth table so I can see what should be on when.

I dont understand why 2 only are coming on and not the third they all have the same Resistor
I am using all the same Red LED's
I do not know where you found such low output current.The datasheet for the4029 shows only approx 2mA at a 12V supply.
I do not know if any simulation software has accurate models for Cmos logic output current.I will do that. Can you suggest software for simulation.

Simply build the circuit and test it.
I have also put the tri colour LED into the circuit Blue and Green Very dominant. If I was to put larger resistors in for the Blue and Green would this bring all the colours to similar intensity.
Again THANK YOU for all the help
