Hi there I need some help. I am new to chicken raising. I had two hens start laying and four pullets. I fed them all lay pelletd when the two hens started laying. Now my 4 pullets are 23 weeks and no sign of laying. Could the lay pellet harmed them? One is a RIR, 2 easter egger and one BCM. The two laying are an orpington and california white. I appreciate any feedback. I am not losing patience yet...more concerned at this point.
