I have read that egg production goes down in winter. I expected to see it in my girls (they were born in February of this year) by now, because we have had winter temps even though it's still fall. I have 8 girls (and 1 rooster)...the rooster and two girls are Barred Rocks, and the other 6 girls are a Barred Rock cross called Commercial Blacks. I am still getting 7-8 eggs a day. Do all chickens start laying less? If so, when should I expect to see a decline in the amount of eggs I get a day? Thank you!
