We purchased 8 RIRs and 1 rooster on Sunday, we don't know how old they are but were told they have laid eggs in the past, but they are not laying eggs since arriving at our home. We have them in a 10X8 house with 4 nesting boxes and lots of roosts, but all we find in the boxes are poop. We allowed them to free range immediately but also gave them the standard chicken food from the Tractor Supply Store. Any thoughts? Were we hoodwinked into purchasing 'old' hens?
