I have 5 Columbian and 5 Silver Laced Wyandottes and they are proving to be the very nearly perfect chicken to me. The began laying at 19 weeks and have laid an egg consistently every day since. They are by far my best layers. I do have one Columbian that goes broody about every other month so I may just let her hatch out some eggs next time. It has to be frustrating to her to sit and have nothing to show for it.
