Hello everyone! My babies are 6 weeks old this week. Since about week 3, I've had my suspicions that one of my 2 wyandottes is a rooster. The 2 wyandottes look completely different from each other, and one has begun to "fluff" when I go by their area. Today I moved them to their coop and let them play around in the enclosed run while I set up the food/water/etc, and my neighbors dog started barking. The chickens all ran to one corner of the run, except the chick that I suspect is a rooster, which ran towards the side of the run the dog was near and seemed to "protect" the other chicks and very fearlessly fluffed her/his feathers. here are some pictures of the wyandottes: The one I think is a roo: Let me know your thoughts!
