I have 3 buff orfingtons who were old enough to lay but weren't laying in the coop. I just found out where they are laying and found about 9 eggs. They aren't cracked but they've been outside in 15 degree overnight weather for at least a week. Daytime temps were up to 60 degrees. I assume they have frozen, then thawed, then frozen again (south facing shelves), then frozen, then thawed again. Any chance they are still good or should I just toss them?
