Some of the first fresh things that I was ever able to get Tweety to eat... were nastursiums (flowers and leaves) that I had grown from seed in a hanging basket and basil flowers... clipped to the side of the cage... he also loves marigold flowers....
This last summer I had cheap planter boxes that I had gotten at the local dollar store... and planted swiss chard and kale to grow for fids in them... when it got hot.. I just moved them in and put them in a sunny window...
I have to grown organic because I can not be around most chemicals .. due to allergies .... and I grow/start most of my veggies from seed .... because I don't know what kinda chemicals have been used on them prior to purchase..

you would not believe some of the growth chemicals greenhouse growers use on seedlings.. even veggie and herb ones...
If I buy seedlings.... I always wait for fresh growth... before harvesting or using for me or fids.... even pinch off blooms ie tomato because even they can be contaminated by some chemicals.... trim back herbs, and wait for new growth... before use..
Parsely and spinich can inhibit calcium absorption... so would advise to feel sparingly.... only once or twice a week ............
Have found out recently that the majority of fids LOVE snow and edible pod peas.... just don't feed sweet pea, they are pretty and smell nice but poisionious to fids ...
swiss chard and kale are easy to grow... and good for fids also.... can even grow in your area during summer.. in shady spot if kept well watered.... along with leafy lettuce varieties, most good in trace minerals, vitamin k and other vitamins...
Broccoli .. if you cut the main flowerettes... small ones will grow from side... for a second crop.... this works with some other members of the cabbage family also....
Before you plant in the ground in your back yard..... would ask landlord if he has sprayed bug or fertilizer in the last couple of years, or he knows whether previous tendants did...... if so... the soil may be questionable for birdy/human veggies....
Just a few thoughts... and possible suggestions....
