With the store eggs - I couldn't figure out the date on the carton as to when they were packed, but they were a sell by March 1st (I think). Oh well, it was worth a try! Now for some fresh eggs from a local BYC'er. I am just hatching the eggs for her because I can't REALLY keep any more chickens, but she understands the need to hatch!! Good luck to everyone's upcoming hatches!
