I have 5 white rocks that were laying 20 to 30 eggs a week on average. In March I purchased 7 chicks from tractor supply, then 3 weeks later I purchase 8 more chicks. Since the first batch my hens production dropped by half, then when I bought the other 8 production dropped to 6 to 10 eggs a week!! I'm very frustrated and thinking of putting the adult hens in freezer camp, am I making a mistake or should I give them more time to get adjusted, my patients is running very thin.
