I got 3, one day old, silky/banty chicks. I am pretty sure that Dora (far left) is a roo but he hasnt crowed. they are only a month and a half old so i dont expect him to crow yet. over time i am starting to wonder if Tigi (far right) might be a roo. she/he is the biggest and the most silkyish(?).It also is the easiest to hold but doesnt approach you on its own. what do you think? pullet or roo? left to right.
