Yes I do until soft and no othermix ins than water . I put a half cup lentils in 1 and a half cup water and cook until soft you will notice the lentils soak up nearly all the water. That amount feeds my flock on 11 birds. Be sure to put them in a large pot since they expand. I've never fed them raw but I'm sure you could

. Be sure not to burn them because it smells really bad, talking from experience

. I hope it works for you and happy laying!! One more thing, dont feed them everyday or it'll give your chickens some runny droppings
