I've followed the instructions but left it on stage two longer than instructions mentioned due to having problems getting an opportunity to change it. Now I've had it as it is supposed to work with the bolts removed and no chickens are stepping on it to eat. They seem humgry, refuse to get near it and have stopped laying. It has definitely stopped any rats, andy feed bill is definitely lower. Should I wait it out some more or give th food? It's been a week or more.
