My 14 week old br roo's and pullets are either practicing really hard or mating already! Call me old fashioned but they are a little young for this right? This is my first flock but my chicken bible aka Raising Chickens for Dummies says they normally dont start laying until about nineteen weeks. . And i know you dont need roo's for eggs but is this a sign that they are getting to that age where i can start expecting eggs?
