I was looking online for ways to sex baby chicks and found this chart someone drew: see attached file I wish I could give proper credit to the person or persons who drew it, but have not found any names. But I’m posting it here to ask all of you, is this basically true? Or is it only true with a certain breed? Do male baby chicks not have any tail feathers by age 2 weeks? Or is this only in general? Thanks in advance for any replies.
