I'm sure this has been asked hundreds of times: My flock of pullets are 18 weeks. Of course I'm like and expectant grandmother waiting breathlessly for the first egg. At this point, I feed the "start to finish" crumbles, some scratch and just introduced layer pellets. They seem to be waiting however for the treats.. pumpkins, pomegranates, and zucchini I offer daily. They don't finish any of the "grain" feed. Are they getting enough nutrients to lay? Will they be slowed down by the shortened days and cooler weather? Am I over feeding? YIKES!
