I have two Blue Andalusions that free range in our back yard. They are just six months old and recently started laying. Today I found six eggs under a pine tree in our back yard. I don't know how long they have been there. I'm pretty sure not more than a week since I just started finding eggs in the nesting box in their coop as well. How do I know if they are safe to eat? I'm in Iowa and the high last week was 80 but the last several days it's been much cooler. Thanks!
