Eggs will last a long time if you don't wash them. Some people leave them out a week and then sell them! Once you wash them, you have to refrigerate. Try not to wash them, but if you have to, do it right before you eat them. Takes some getting used to.
Soooo, CONGRATULATIONS. I can't believe your chickens are laying so soon. What kind do you have? Chickens are fun and the eggs are great. I like the additional compost, too. We also get to see more wildlife--unfortunatly, predators. All part of the fun.
Our chickens stop laying around Oct or Nov if we don't give them additional hours of light. So we have a light on a timer that turns on early in the morning. We found that if the light stayed on in the evening, the chickens went to sleep anyway and it didn't work. But turn it on at 4 am and presto, eggs. Not very green of us, but we are spoiled by those eggs.
