i have 7 pullets that have not started laying yet and all of them are 6 months old. Two Delawares, two welsummers, a red ranger, and three salmon faverolles. Should they be starting soon? The two Delaware’s and the ranger have very red combs and have for a little while so I figured they should be laying real soon if not already. The salmons and welsummers are just turning pink so I figured I could have a bit on them. Is this all normal?
