Welcome to BYC. Glad you decided to join our flock. I've never had a automatic game feeder, so I can't comment on them one way or another, but I would suggest posting this on our Feeding and Watering Your Flock section at https://www.backyardchickens.com/f/12/feeding-watering-your-flock. Please feel free to ask any questions you may have. We are here to help in any way we can. Good luck in getting the information on the auto game feeders.
Definitely stop by our Feeding and Watering Your Flock section for more help with this. Michael has left you with the link. Here is a link to our archives of other threads started on automatic feeders. Maybe one of these will give you some ideas...https://www.backyardchickens.com/newsearch?search=automatic+feeders
