We saw Michael's tube training trick with Truman and decided to give it a go with Velli (Sun) and Dac (Jenday)
Seen here is Michael's Truman doing the trick as he explains it:https://www.youtube.com/watch?v=1d4BLDArPd0#t=39
So far so good with Velli. She's still a bit hesitant, but we only have to target her through the tube once and she gets the idea. Dac will do it with targeting, but is still warming up to the idea and usually just watches Velli from one of our shoulders.

It took a couple of weeks of just leaving the tube next to their cage and a couple of sessions before they reliable approached the tube.
