My girls are starting to lay again. Been getting 1 egg every other day for a few weeks, yesterday I got 2 from my 5 Bared Rocks, my 1 EE has not given any yet. :)
Frigid here this weekend also but my girls will have no heat. Ventilation is more important than heat I have read. I have my run covered with plastic and with sunshine its much warmer for them during the day.
