My first frozen eggs

I hate it when the eggs freeze. I would consider keeping the girls indoors if I were you. As for the eggs, make sure there is plenty of bedding in the nestbox, and consider heating if your coop is not well insulated--no for your chickens, but for your eggs.

 

Yes, put lots of bedding in to keep the eggs from freezing. I would put heat in the coop to keep the eggs from freezing and make sure your coop is well insulated.
