Grow what you like to eat. And what your chickens like to eat. Truer words were never posted!
I'm not a big kale fan, it's... ok. But the birds like it and so does a good friend of mine, so I plant a row. I've tried a few new things this year. So far one runaway hit, and one total flop. A few things that I threw the tops of the plants in the run, but I won't grow them again.
I like to preserve things as shelf stable as possible, as it is just about a given we will lose power during the year, and sometimes for 2-3 days. So I can what I can (ha ha) and dehydrate some things too. Potatoes, onions, garlic and squash sit at cool room temp.
Butternut squash is the only squash I grow. You get a LOT of squash with that big neck, and they get sweeter as they age. By Thanksgiving, they are better than sweet potatoes, to me. And the seeds are a good snack that now I have to share with the chickens. I toast mine. They have to eat theirs raw.
I'm thinking a chicken run around part of the garden work for me next season too. The garden is fenced, so it would have to be a lean to type of thing; too many aerial predators.
