We have a sweet corn grower in town thats allowed us to go through the fields after they have picked through it. There is still alot of editable corn left, some not as pretty as others. We send the spent ears out to the chickens..ones we ate and ones we have cut off the cob for freezing. Others, the not so pretty ones, we have blanched and frozen whole and thaw out and they love that to. They have their regular feed and they free range. Corn isn't their only source of food. If we had the freezer space, the chickens could have corn all year long.. Now how much would be to much to give them? Thanks!
