So I Bought 7 chicks From our feed store, supposed to be all pullets, and then I bought 5 straight run chicks in hopes for A roo, now all chicks are approx the same age, all hatched within days of each other. I told the lady I got the 5 from I wanted a Roo, and she picked them according to their tail feathers. She said the ones with longer tail feathers are "usually" males and the shorter tail feathers Are "usually" females. So i got 2 with longer feathers, and 3 with shorter feathers. Now when i got home, i looked at my 7 feed store pullets, only to find all my original chicks have longer feathers., so in this instance, I sure hope she was wrong! I'm including a picture of two chicks from the straight run batch, one on the left is shorter tail feathers, one on the right is the longer feathers. All the straight Run chicks are the same pure bred Blue laced red Wyandotte.
