I live on a one acre lot in a private neighborhood and I already have a garden. I want to get about 6 to 10 chickens for pets/eggs. I was thinking of putting the coop in the same area as the garden. Will they A)keep the garden free of pests and weeds or B) destroy my vegetables ? I am hoping to start design of my coop and construction so that I can get the chicks early and start spending time with them and getting them comfortable around us.
