That sounds awesome!
I started my fruit trees in pots from cuttings of my Grandfather's fruit trees 3 years ago. We're renting a house with a yard now so my trees get more sun than they did at the flat. One day when we have our own house I will plant my trees.
If you have yard space you could also keep quail instead of chickens. They need less space and are much quieter so they are well suited to urban spaces.
Funny you should mention quail, I actually already wrote a bit about them!
I hope you get to plant those trees. I struggle to keep anything alive in pots for very long.
