Keep eggs 33 to 40 degrees on inside on bottom shelf........not on the door....not in the egg keeper...original carton will keep 3 to 4 weeks past the carton date. Do not leave out more than 2 hours Throw out cracked eggs. Or mix them up and blend with water and spray the plants outside to keep deer away. You can do the cold water test..........fill a big mug with cold water..........if the egg sinks it is good........if it stands on one end it is getting ready.........use that first.......if it floats make that mix to keep the deer off the bushes & trees........or throw them out. It is not advised to feed bad eggs to pets as they can get very sick.
