I have 5 silkie chickens 3 1/2 weeks old. 3 from My Pet Chicken who are "female" which are the smallest 3 (black,white,buff). I also have 2 that are straight runs from a Silkie breeder, the 2 biggest ones (blue grey,splash) were born 2 days before the other 3 chickens from my pet chicken. My question is if the Splash (white and grey one aka the biggest) one is a rooster. We can not have roosters in my city. I don't know if it's too soon to know what gender they are. Here are some pictures let me know if there's other pictures you need.
