I too have ordered five chicks, and two have now turned out to be roosters. One, a bantam, has not crowed yet due to my easter egger being the dominant one. I was about to try a no crow collar, but read somewhere on this post of a person putting their rooster in a small basket/box in the evening, and then letting him out in the morning at a respectable hour. Well, I tried it this morning (using a small pet crate) and it is working! The rooster cannot stretch its neck up and out to gather a big breath, and therefore is in a roosting position so he cannot crow. It is working so far, I hope I can keep this up until I move to the country!
