The "normal" behaviour would be to draw in energy, when they emit it, you will feel depleted and tired.
Apart from that they can be closed/blocked or active. Sometimes some chakras can be partially blocked.
The best way I found to diagnose how a chakra is at a given moment is by using a pendulum.
If you keep a pendulum straight above a chakra, you will notice that soon enough it will start spinning.
By observing how it spins we can understand a lot:
If it spin clockwise, the chakra is open and functional
if it spins anticlockwise it is generally considered to be blocked or closed (I say "generally" because there are exceptions, which I shall explain later).
I will describe some of these patterns in a later post. I prefer to keep posts short so that they are easier to read and allow for more precise breaking down of topics. I hope you agree!
