Thank you so much
I realized I never followed up!!! So sorry!! So here's the end of the story: On Super Bowl Sunday (which was day 18, lockdown, for the chicken eggs she'd been sitting on) she decided to move to the nesting box next door. I found the eggs, likely about a half hour after she had moved. They were already cold (it was below freezing all that day) and, upon candling, dead. I was so mad at her!!!! She tried to be broody for days after that but for some reason she would change nesting boxes every couple hours and lay on different eggs. I had tons of eggs that had been 'incubated' for about 24 hours. Thankfully she's over it and laying her own again. I need to get her a 'man.' (a Tom, lol).
