I have four polish chicks about 7.5 weeks old. This is the only one that is getting these things (I am a new chicken owner and am embarassed that I do not know what these things are called) under his/her beak. Do you think that this one may be a rooster? Or do all polish get them? I know this isn't a good picture, but this is what the others look like. I am just very excited about my chickens! I am hoping that this one is a rooster and the other three are hens!!!
