When it gets wet, it spoils and molds, that's why your chickens won't touch it.When my feed gets wet and ferments...even a little, my birds will starve to death before they touch it. How do you make them eat it?
food+water in a food safe container and stir it. Let it go for at least three days, stirring once a day .
Sometimes they will look at it like you are trying to poison them at first, but that's just because it's something they aren't familiar with yet.
