I got my first 3 eggs yesterday! This is my first time having chickens so I'm still new to everything and it has been an interesting experience so far. I have 11 hens that I got from TSC at the beginning of April. I was told that the earliest that people reported eggs was after 12 weeks and that 18 weeks was normal. Mine are 17.5 weeks so I've been waiting for eggs since week 12 and yesterday was like Christmas when I found them in the coop. What do I have to do to make sure the eggs are cleaned well enough before we can eat them so nobody can get sick from anything that may be on the shells? Also what is the shelf-life of the eggs before they are no longer fresh? Thanks.
