Viability of raising quail and microgreens for everyday use and survival?

Hello all.

I came across a coworker who grows his own micro greens in his kitchen, I became interested in this and would like some more information.
Is it viable to grow this from a prepper stand point, in say my two car garage? Also I currently already raise my own quail, to feed my hawks and falcons. Would these be viable to eat in a survival situation?

(i currently raise in the area of 3000-5000 quail at any time) I also have at least a 1 car garage area or I could possibly build a greenhouse (depending on cost) to raise some form of greens.

My goal is to supply myself year around with both meat and greens.

How practical is this idea?

Any info on this, or other ideas would be great.
