Yes, I don't bother in the warmer months, because they get chicory, and other greens.I've noticed with the sweet potato vines to pick at around their run combined with the scratch and peck feed my birds barely eat any sprouts I give them. I'm thinking during the warm months they might just not go for this. I will still try it out though this winter and see if they will go for barley fodder better than the sprouts I've tried.
So it makes sense to grow Fodder seasonally for some of us.
