The Dine-A-Chook feeders that I bought on line have been so terrific. I buy my girls the most expensive organic feed and used to get through a 20kg bag in 3 weeks. Since installing the Dine-A-Chook feeders the bags last me 6 weeks - with very little feed on the floor of the coop. I have two feeders for 10 chooks and they last me a whole week before I have to refill too, so keeping chooks just got a whole lot easier for me. Also we've has some big rains here on the NSW north coast, and your feeders keep the grain perfectly dry, even when the rain is torrential. So awesome. The girls took to the feeders straight away, and they're looking healthy and happy. Couldn't be happier with my purchase.
