I have a flock of four chickens and they have all been laying very sporadically because of shorter/cloudy days (no supplemental light--I'm okay with them taking a break). I have not had an egg from any of them in the last four days. Then, this morning, it appears that two of my girls each laid two eggs. I have one EE and two blue eggs this morning and two brown eggs from my Delaware. Is this normal during the winter? We did have a somewhat sunny day yesterday and the girls were basking in the sun quite a bit in the afternoon--could that have made the double, double-egg day?
