This may be an incredibly green horn question but I don't know the answer so I'm asking anyway! We keep our coop very clean but despite our best efforts, every now and then the chickens get poo on the egg shells. Are they safe to eat when there is poo on the shell? Is it any safer if I wash the poo off the shell or is this going to make it worse? (I read somewhere that once the shell gets wet, the protective coating is removed and the shell is now permeable to things like poo getting in and contaminating the egg with salmonella.) I want my eggs to be safe for my friends and family but it seems like such a waste to toss out an egg because of a tiny speck of poo. Can anyone set me straight? Thanks!
