We bought 8 chicks from a breeder ranging from 2 to 4 weeks old. We bought them with the assumption that they were hens but knew it wasn't 100%. About 4 weeks have passed and we think we might have mostly roos. We have 1 Rhode Island Red, 2 black sex link, 1 Dominique, 2 Black Australorps, and 2 that are suppose to be something else but they don't look like the others lol. Do some of these look like roosters to you?
