I have 5 cockatiels and with the possible exception of 1 they all like to get wet one way or another.
The thing is it's only when THEY want it. I can mist them anytime but if they don't feel like a bath they will try to get away.
If they like the idea the will do the Tiel "rain dance".
2 of my Tiels like to splash in a shallow bowl but if they don't feel like it the ignore the water.
