My girls went from 2 eggs a day to 6 in about a month, and the change was one thing
I stopped tossing their eggshells in the trash and started crushing them into the feed, just a handful twice a day. Took maybe 3 weeks to see it, but now I get 6 eggs from 7 hens and I want to know if anyone else noticed this or if my hens just finally hit their stride.
