Lazy Gardener
Super Self-Sufficient
It didn't go to seed? Any time I have swiss chard winter over, and it does so fairly regularly... it promptly goes to seed. I can harvest about a qt. of seed from a single plant.
If you already have the seeds for things the chickens will eat, throw them out there. Those rascals eat every day and love fresh greens. Mine free range and they still jump on veggies! (and chicken feed as well ) So I like to dump all I can to them to keep that feed bill down. By the way, mine love turnips and they can stay in ground until you pull & feed. You often have rabbits, give them some greens.
I'd say, look at what you eat and can grow. Plant as much of that as you can use. No tomatoes? That's the one thing most feel they can't go without. For me, that is true.
Also, once your plants are pretty well established, the chickens will go in and eat bugs for you. Yeah, some veggies, too but not so much destruction except very young plants. Those are toast!
Limas? Melons? Pumpkins? Winter squash? Sunflowers (seeds)?
You've had good success in the past, some failures -- we all have that. It's a lot of work!! Maybe you need a break? Ask your wife what she thinks you need to plant. May be different from your idea. Plenty of beans? Remember those kids are growing and so will the grocery bills.
