How much corn on the cob is okay to give? Can it be their whole feed ration for some days? I ask because I just picked the "reject" corn from the field our landlord has, and I have a LOT of it. I plan to freeze what I can so they can have "fresh" corn in the winter too. Also,we have some apple trees and they really enjoy the fallen apples, which ALL have grubs in them. Is it okay to freeze some of those and give them too? That way they'd get some bugs in the winter too!
