I am a brand new chicken owner. I have three beautiful young hens. Their age range is between 10-14 weeks. The guy at Tractor Supply said I should be feeding them layer feed. According to what I am seeing on here, it is too early for layer feed and I should wait until spring when they are ready to lay to feed them layer feed. What should I do? I trust the folks on here more than a kid at Tractor Supply. Any help is appreciated.
