I am thinking about designing a simple tractor that is the width of my garden isles, putting the chickens in for an hour or so each day -my isles will be weeded and my chickens happy. My question is- do I have to wait until evening? I don't want to take the chickens away from the coop, if they haven't laid yet. If I put a chicken in the garden and she needs to lay an egg, will she be distressed? We let the chickens in the garden in the fall- boy did they have a good time and I swear we didn't need to rototill, they did such a great job!
