Sorry for all the questions......I'm just trying to absorb as much as I can about the goat world. Do most of you leave your goats out at night? I have just two pgymies and no big dogs. I have been locking them up at night....they are so little right now and we do have coyotes around from time to time. Second question.......can I leave them outside during the day in the winter with access to their shelter....and when is too cold, too cold? We can get quite a bit of snow....will they go out in snow? Third question........should I have a heater or heat lamp in their barn? Thanks for you advice!
