I have some BLRW and SLW chicks that are a day old. I am wondering if you can color sex them by the chest or head colorations? I have not seen any info online that tells me how to do this. Even the RedLacedBlue website doesn't explain. However, it does show two different chicks, a cockeral and a pullet, at just a few days old. So, I guess there must be a way to tell sex? Any opinions would be great!
