I have 7 four week old chicks. They have a feeder that is one of the long metal kind--with the sliding top. They constantly kick the pine shavings into it and they can't get to the food. Within minutes, it's full. I am moving them into the finished coop this week and don't want to walk down to it several times a day to check the feed. I tried putting it on a 2/4 but they get on top and knock it over. What else can I try? I thought about screwing it to the board so it was heavier?? I don't want to buy a new feeder if I don't have too. We are building a PVC feeder for the coop/run, just not quite there yet. Any suggestions?
