This will be our first winter having geese. This is my question.. They will be out doors all day while there is light and brought into their coop when dark/night. What should I do when it's dark at 4:30pm? Bring them in, but keep a light on for a few hours? Also, is it ok that they don't have their pool in the winter to bathe in? I will have no way to keep it from freezing. Also, other than romain and kale, what greens should be offered when the ground is covered with snow?
