Feedack from Mrs. foxfield: Eggs frozen in shell are not that great. Shells crack in the freezing process but are easy to remove by running under cold water, but fully thawed eggs are kind of rubbery. She freezes them this way as a backup for when the hens slow down. She wants to try the scramble and freeze method. Thank you for the tip.
You bet.
Keep me posted, if/when she does try.
