I am going to plant a vegetable garden starting now Jan. 26. I will be planting onions, shallots, and leeks now. Next I'm planting Swiss Chard followed by tomatoes, cucumbers, sweet peppers and eggplants. There may be some additional stuff also planted. Are the chickens gonna require me to fence-off my garden? They will have access to acres of area to forage in, without needing to invade my garden. Do they bother some vegetables worse than others?
