Does anybody mark the date on there eggs with pencil the day they were layed by hens? And is it harmful to chickens, hen or rooster to feed the eggshells to them that has date on them from pencil lead? I don't want to harm them in any way. Heard the eggshells are a good source of calcium. Also, what scraps or food are a good alternative in addition to the scratch and feed. Such as vegetable or fruits rinds, etc. I don't know what food items are acceptable for feeding them scraps, etc. other then there feed. New to raising backyard chickens, etc. Thank you for any advice or information given.
