I am only getting 2-3 eggs per day now from my 3 laying hens. But when the pullets start laying in March or April, I'll have 16 laying hens every day. I do plan to sell some eggs to friends and neighbors to help curb the cost of feed. I am wondering if I could number the eggs or date stamp the eggs with a little stamper of some sort? I could use a gel pen, or perhaps a sharpie. But I don't want the ink to affect the eggs. Have any of you ever tried something like this? If the ink may soak thru to the egg, I won't do it. But I have seen eggs in the store that were stamped. I want to do this to mainly keep track so none of the eggs get bypassed and left setting for to long. I want to be sure that all the eggs are used or go out in a timely mannor and not left sitting, or overlooked for to long. Any feed back will be appreciated. Thanks.
