Hi all, Long time lurker here, just now signed up but this site was the inspiration to start a small backyard flock in 2009. I keep three Rhode Island Red hens and one rooster. This spring I built an incubator and hatched out around 30 chicks just to see if it was possible to do so with a home built incubator (really easy, the temperature doesn't have to be perfect if you will settle for a lower hatch rate), then sold the excess birds off using Craigs List. Starting out I didn't have a mouse problem but the last year or so their population has exploded as has the feed bill. Looking around I saw the very nice grandpa feeders but just couldn't bring myself to spend that kind of money. So I built my own. The hens took right to it after about five minutes of me opening it so they would start eating, then closing it. it holds about a half sack of feed, 25 #, and it is adjustable for different size chickens (or different size rats!). I wanted a small footprint so it is around 11" square and 19" tall, was suprised that it held a half sack of feed. Not the best video but better than nothing. I didn't use the overhead treadle design because I thought that a chicken could get trapped. This design will just push their head out of the way when it comes down. So looking at this one, what did I miss when building it? Too small? Too large? How would you make it better?
