Our ladies' egg production has dropped off sharply We were getting 10 or more eggs a day from 14 hens. Now we are only getting 5-7. Using the same feed and oyster shells for them. It's only gotten up to the lw 90's so far.We hae fans in the coop and they get all the yard time they want. It has rained here almost daily for about a week and there hasn't been much sunshine, Muddy and dreary most of the days...any ideas what might be up??
