We are going away for 2 weeks. I would like to make chicken care as easy as possible. Can I use a gravity water feeder for our chickens (like the kind you would use for a dog or cat)? We currently use a gravity food feeder with no problems. We currently have a chicken waterer hanging in the coop but its the kind that needs to be taken down and twisted apart to refill. I just feel like the ability to fill from the top will make things so much easier.
