ok, I have a big planter box in my chicken yard. It's about a foot high 3ft long and 4 ft wide. I have the entire thing filled with dirt and at the top I have half inch welded wire about an inch or inch and a half above the dirt. In this big planter I throw wheat and flax seed and water it through the welded wire. As the plants grow up through the welded wire the chickens graze on it. Now my question is, is the flax plant as good as eating the seeds or am I wasting my time letting them eat the plant when I should wait til the plant goes to seed? What do you think?
