Well, I will still post a new pic every week but, by week 3 maybe you can tell. If males and females grow at different speeds I can keep comparing With another chick.
I can post a pic of Blaze and mother chick so that you can compare or/and contrast, the others are females I think. I heard you can tell by the wings or something like that between day 3-7.
This is Blaze. He/she is About a week old and is a Rhode Island Red. Is it a boy or girl? I think he/she is a boy, what do you think? If you need more pics tell me.
