I have been reading up on adding flax to the chicken feed to increase Omega 3 in the yolks. I was wondering if I could just plant a lot of flax around in my gardens and give it to the girls when it goes to seed. Can I just toss the entire dried flower/seed part into the run? Should the seed be shaken our first? I think they might enjoy it if I tossed in one or two a week. The second question I have is sunflowers. Can I just grow some giant sunflowers, let them dry out, and then give the entire flower to them? Is there some type of sunflower they like better? Are there any other treats I can grow in their side of the yard that you can suggest?
