I have a 25' x 25' area in my backyard that has been fenced off and cleared for a vegetable garden. I was thinking that it'd be nice to allow a few chickens to roam free in the garden but I am concerned that they will eat the vegetable plants down to nothing. I need to build a coup for the chickens to have a safe place at night but I was hoping for quasi-free range during the day. Will this work or will the chickens eat the vegetables? I appreciate any help..
