Ive had my Hybrids for 4 weeks they are now 28 weeks old. They are in a run/coop during the night and free range for 5 hours during the day. Ive not changed their food of layers pellets a.m corn mix p.m with meal worm treats. We have gone from 3/4 eggs a day to 1. They are happy girls and don't appear to be egg bound though I have seen a couple of blood streaks in their poop. One hen is a bit loose! All hens are fully vaccinated wormed and paracite treated with Verm-X. Is it normal to have such a decline in egg production or am I doing something wrong?
