Target training. This is your best bet, honestly! Teach Echo to target simply by walking around at first, then you could set up two chairs with their backs together and start working on teaching target training between the two chairs. Start with stepping from one chair to the other and back again. Repeat, repeat, repeat. Then move one chair maybe an inch away and target again. Repeat, repeat, repeat. Keep spacing the chairs further and further and rewarding the desired behavior. As Echo's confidence increases, she can start working on hopping from one chair to the other, then a hop with a flap, then actual flying. If at any time she hesitates, then go back a step until she's ready to proceed further.
Once she's good at targeting between, you can start teaching her to target to other areas around the house. You may need to start from the beginning at each location until the behavior has been generalized enough for her to understand. You can target her and cue, such as "cage", "perch", "gym", etc.
