Specifically How long will they last if they are not refrigerated. I saw some really pretty dyed brown eggs on another post https://www.backyardchickens.com/forum/viewtopic.php?id=161261 and it got me thinking. When my kids dye eggs we always put them in the fridge so they don't spoil, but then no one can see them. I'd love to leave them out for display, at least on Easter day. So how long would it be safe to leave them unrefridgerated?
