DH and I were quite happy in our apartment for several years. We had a garden, and fruit trees: apple, pear, pie cherry. I experimented with lots of herb growing and drying and mix-making, and I learned to grow tomatoes in an earthbox. It was in a two-family house in a neighborhood where we were surrounded by Italian widows with gardens....it was a wonderful place to learn. Maybe you can find something just as wonderful.
When I was a kid, before the family moved to Maine, we lived on a tiny, tiny plot that had no light for a garden. So my folks got some garden space from an older widower. We would spend Saturday afternoons working in the garden. I will never forget those fall harvests. Or the wild peaches he let us pick, or the swarm of bees he had my dad help him capture. SS with NO land whatsoever. It can be done.
Oh, and Dad still managed to get some free chickens and slaughtered them in the garage!
ETA: AAAANNNNNND.....the folks are now in a little subsidized apartment....and Dad has quite an expanding veggie and flower garden there. He keeps his chickens here, and his pig is with my pig. He kills my chickens and he gets half. It can be done.
Remember to be open for any opportunity! Where I live with my tiny yard even a big garden was out of the question ... at first. Then after meeting neighbors I was OFFERED a vacant 1/2 acre lot behind an apartment building. It had been gardened for years by the father of the building owner, but he was getting too feeble and the owner did not want to have to PAY a lawn company to up keep that lot. Just by making his acquaintance and "farming" my tiny yard responsibly earned me the allotment (God's allotment to me in my time of need)! I have been gardening there FREE and pretty much whatever I wanted to do for about 8 years and through TWO apartment owners!! I am having trouble now with my arthritis and neuropathy, so I am passing it on. (because of location EVERYTHING must be hand worked)
Even in a tiny apartment opportunities are there. When we were first married we lived in HUD housing one bedroom apartment. There I found out that we could grow "flowers" in the bed beside the apartment. My flowers all grew tomatoes and pumpkins!
I made it 2 months living with my parents just after the birth of my youngest. We were replacing the water lines in our mobile home because they had frozen. We dug a trench & buried 800' of water line to the house, replaced the pipe, dug the septic, had it laid, got the electric run & hooked up, even with the rain & sleet of January. We had to get OUT!
Keep your eyes open and your ears peeled, something will come up.
Best of luck to you and hubby no mater what you decide. So you don't miss chickens too much, just remember quail CAN be raised in doors with a little planning
