I don’t know if it works yet or not. I just got them. I chose that bc it holds like 12 gallons of water and the feeder is gravity fed holding 50 lbs. I have a smaller feeder that holds 20 lbs too. I got them long b4 our trip just to see if they work well. Don’t want my chickens to die!!So it doesn’t hold enough feed for the time you’ll be away? The only thing I’ve found that fits that bill for me is five gallon bucket feeders and waterers. Gravity feeders too, but the five gallon for water.
I hate plastics

Just seeing if anyone else uses these and how you like them
