They were the talk of the farmers along our Line. I'm always amazed at how such a tiny seed can grow so massive. Bees LOVE these sunflowers as do the birds once they go to seed. Sometimes the bees get so tired you will find them attached to the flowers, dead from exhaustion. It kinda freaked me out the first time I saw them all, but that's the life of a working bee. You can harvest the seeds for personal use or they can be used to supplement your chicken feed. Harvesting I have learned over the past few years is extremely important. If you don't do it correctly all of your seeds will mold and go to waste.
