I have four hens newly laying. 2 weeks ago I got an egg every 3-4 days. Last week I think one hen laid a soft shelled agg and a hard shelled egg but I haven't had anything all week from anyone. Can newly laying hens just stop? I just let them outside into a new run. Can that cause them to stop? Or maybe a change in the weather? Last week we had temp close to 100 but this week it's a high of 60. Thanks!
