Hi everyone, My baby chicks will be 4 weeks in a day or two. I have two mixed breed chicks (black autralorpe mixes). I got them from a farm, that obviously is not equipped for sexing. They both have a great temperment from being hand raised since hatching. They look the same in every regard, with the exception of their tail feathers (and coloring). One of the birds already has tail feathers that are more developed and standing more upward than the other one. Not straight up all the time, but defintely more pronouced and vertical. I am not too sure if I am just stressed out about this, or if they really do start to show gender differences in their tail feathers this early. (?) Since they are mixed, I am not too sure if the one bird perhaps has genetics for more pronounced tail feathers. I am confused!!! Please help!!! We are not zoned for roosters, and I am so afraid I will have to give him back to the farm.
