Hi everyone! I'm new to the forum and new to having chickens, so I apologize for any "stupid" or repeat questions in advance. My oldest girls are right at 21 weeks old and some are barr rocks (all of them were suppose to be girls and all of them were suppose to be barr rocks but we are finding this not to be the case). Anyway, I was wondering if any of you have any experience with barr rocks and was wondering at what age did they start laying? I will also soon be posting in the "What is it?" thread...to any of you that can help me identify my "mystery" chickens! Thanks!
