Chicken Forage Mix of Greens that Chicken Love. Adds Omega 3 Fatty Acids to Their Eggs. 1/8 Pound. 1/8 Pound. Plant a Tasty and Nutritious Mix for your Chickens. This is a Mix of Perennial and Annuals that should persist with Minimal Summer Water. Plant annually after danger of frost has passed. One way to get Omega 3 Fatty Acids in our food is to eat eggs from chickens raised on a diet that promotes the formation of Omega-3s right in the egg. Keep your birds away from the newly seeded area or they will eat the seed before it has a chance to germinate. When the mix is 2-5" tall turn the chickens loose on the planted area until they have eaten the grasses about half way down. For chickens that stay in runs, plant some Forage Mix in a 17" square flat. Add soil, sow thickly, follow the growing instructions above, then place the flat in the chicken run and let them eat it all up. Marde Ross & Company has been a Licensed California Nursery since 1985.
