Hello, I apologize for asking questions that have probably been asked many times before, but I appreciate any help and advice you can give me. First off, I have a small, backyard flock of Plymouth Barred Rocks who are about 1.5 years old. They are currently housed in a shaded, elevated outdoor cage while their permanent hutch and yard is under construction. In addition to layer pellets, they are supplemented with table scraps and fresh-picked dandelions, clover, and grasses daily. There are 8 hens and one very active rooster, so I think that the eggs are all probably fertilized. It is summer in Indiana, so the daily high temperatures are anywhere from the 70s to the 90s, with occasional days peaking over 100 degrees. My first question is regarding how long fertilized eggs remain technically safe for consumption under these conditions. I know it is ideal to collect eggs several times a day. But, if I am only able to collect eggs once every 24 hours, will the eggs still be OK to serve to my family? I keep thinking about how hatching eggs can be left out for weeks before placing in the incubator and I wonder if that means that a fertilized egg won't spoil immediately like store-bought eggs? Does anyone know specifically how many hours an egg can really sit in the nest box before it becomes unsafe? The next question relates to the first: If I find an egg with a small, hairline crack after I have collected the daily eggs, is it edible? The only thing I can know for certain is that the egg may have cracked as soon as 5 minutes prior (during collection) or as long as 24 hours ago (if it were laid 5 minutes after the previous day's eggs were removed). In either case, do the eggs require immediate cooking at high temperature, or can they go in the fridge for a few days? Thank you very much!
