It has been about 2 weeks since my two Easter Eggers have laid any eggs. Before then, they were on a very good one egg per day schedule. Could the weather cooling down (55-65 degrees F during the day and 35-45 degrees F during the night) be causing this? I knew they would slow down, but I didn't know they would quit completely. Also, what temperature extremes can chickens handle? My chickens have a coop, but refuse to sleep in it. They sleep on top of it.
