Hi everyone. We had chickens when I was younger, but these are the first I have kept as an adult. I have two chickens who's sex I am concerned about. The first one is the Giant white Cochin in the first picture along with the other pics. Was bought as a pullet but is showing definite rooster personality traits (was on top of one of the hens today, always last in the coop and sleeps by the door) These next two pictures the individual I am concerned about is the silver/blue one in middle of first pic and back middle by fence in second. Is it a cockerel? This one was intended to be male, but is not crowing and is very timid. It is about 5 months old. Here is another pic silver/blue cockerel? Tail off to the left and giant also in pic. Any help would be great!
