I don't think anyone took offense, nor do I think the necessity of eggs in a chicken's diet was ever in question. Obviously they are fine without the addition. It just seems incongruous to me to feel guilty that a chicken went "through a lot to produce that egg", then consider it somehow...
My chickens are primarily yard art and pets but when the ladies are laying I have far more eggs than we can use. I give them away to family (my in-laws thank me by buying a bag of feed every now and then) and also cook and feed them to my animals. I don't consider it wasting...I enjoy fresh...
