It is autumn. The days are getting shorter and egg production will slow down. Birds will also molt as a reaction of changing daylight hours, hens usually do not lay during a molt.
What I think happened. Around 10/30 I aligned their outdoor run with about 15 straw bales. Large ones. Now prey cant easily see the chickens but they are picking at it. Straw is low in nutrients. I think they are filling their bellies with nothing and the days are getting shorter. Right?
In theory 10 chickens all must be lay 1 egg ever 3 days? The last 6 days would suggest that. Also another note I've never got more than 7 eggs in a day. Could not all 10 be laying. Born April 4th so they all should be laying. Trust me no hidden eggs.
EDIT: ALSO ALL GREENS/GRASS IS GONE AROUND THIS TIME.
