First off, pic not related.

I wanna have a mini farm in my yard. My yard is about 200 sqm of usable space. I wanna have chickens, and feed them with whatever I grow on the land.

With such a small space, is it viable? Also, I know nothing about farming or chickens, so any advice or resources on information would be helpful
