A nice thought but not with chickens roaming free. They consider a spot of fresh dirt an opportunity to live off the land and can dispatch a plant in no time. I have returned to find only shreds of my treasured plant still clinging to life and chicken butts sticking out of the hole.
"What, who ME? She did it!" I have learned to either dig decoy holes, or wait till they go to bed to plant. If they see me with a shovel, they come running.
There is no privacy in the garden with chickens on the loose.
