I live in zone 7, in the west Tennessee area. My chickens have plenty of grass and fresh weeds to munch on right now, but come winter time, the grasses we currently have in our lawn will die. I was thinking on overseeding with winter grass so my gals will have something to munch on this winter. What would be good for this? Have others of you grown winter grasses or other plants for your feathered children's winter diets?
