I have 24 chickens in a fenced in area- about 1/2 acre. They have made it look like the surface of the moon!! The other day I was observing them digging around. I was wondering how many bugs could possibly be in the dirt... Well, as I watched I saw what they were after... They are digging up and eating tiny green shoots, before they even emerge out of the soil. Any hopes I had for anything green, went up in smoke!! I will say, we planted about 10 baby pine trees last year, and they have not bothered them. They also left the new lilacs alone-but they are not green yet, so we will see if they make it this spring. I always kind of chuckle when people think chickens are good for their lawn. Maybe 1 or 2- but not a load of them! Enjoy!
