I'm also looking to get more self sustaining, I started the journey last year and still have a long way to go. This is a nice thread. I'm yet to read all the posts.
I have expanded m garden this year and have not bought green leafy vegetables in several months now, have frozen some and given more to friends. Also getting an abundance of tomatoes that I'm freezing, making spaghetti sauce and giving to friends too. That's about all I have in the garden. I planted an apple tree last year that has given me a few apples this year, I'll need to read more on pruning and maintaining it. Bought two more fruit trees (1 apple and 1 peach) when they went on sale, will be looking for more before fall.
As for chickens I started last year with 9 layers, now I have a total of 47, I hatched 33 this year from some of my eggs and others. I plan on letting the chickens multiply to get a self sustaining flock as opposed to buying meat chicks every year. I know free range and my breeds not being purely meat birds (cornish X) will grow slower but that's the way I was raised and I love the gamey taste.
Next spring I would like to expand on the garden and have more variety of veggies. Will be checking what other veggies I can plant this late.
Failures so far: Ducks
they were easy to maintain and used less feed but they were extremely dirty kept pooping on the deck, hard to process and also could never train them to get in the coop at night by themselves which made it harder on family travel. I was always worried they would be eaten by foxes.
