I used mine up in ten months before starting new ones this month. I suggest using no larger than a gallon jar, since the weight can break an egg. If you break one, it is not recommended to used the others. Also, you can store them flat, they don't need to stand on end, which is almost impossible anyhow and more likely to get cracked.
Speaking of eggs, I am having a terrible time doing boiled eggs in different seasoning. My eggs are almost impossible to peal without looking like I gave them to a hamster. I use my oldest eggs. I tried putting a little vinegar in the water. Today, I boiled them, then transferred them to ice water. Some people in Alaska left their eggs lay out for three weeks before doing pickled eggs. That seems like a long time. Anyone have any tricks? I even wondered if it was the breed but I have three different breeds laying right now.
