I have 3 silky chicks about about 4 to 5 weeks old. Can anyone tell me what to watch for to see if any are roosters. These are pets and I am afraid to keep a rooster as I have a 4 year old that goes in the coop and I am afraid they will be to mean.. I am including a picture of one that I think may be a rooster. And if anyone can tell me what color this one looks to be let me know Its not really white..

Then I have this buff one..
