Hello, just joined into membership. Have browsed the site a few times for tips. Aquired 5 chicks in July now 22 wks not laying yet. Girls in local 4H club, came home with 7 more hens an 1 rooster about the same age. We are quaritining the new ones. Also in process of building larger coop. None of the hens are laying yet size wise about the same all on layer food already. So they're within 4 weeks of each other. Any tips on vaccinations? Looking forward to learning more. Thanks.
