My creamlegbar just played her first eggs in the past few days. I checked yesterday late afternoon (I have been getting one every other day) and there was no egg. I just checked at 10am this morning and there is an egg that was cracked and slightly frozen (it was in the 40's yesterday and 17F last night. Is she laying just after she goes in the coop at 6pm? I don't think it had time to freeze and crack this morning unless she's laying in the middle of the night?
