I had posted yesterday about having to rehome my 16 week old Dominique who has turned out to be a rooster. When I bought my 6 baby chicks I was told there is a 10% chance that they could turn out to be a roo. Me having to re home" Charles" ( who up until the other day was Charolette) is making me very sad. I have had him since he was 2 days old. He is a very friendly guy. I attribute that to interacting with him and the girls on a daily basis. If there was a way for the hatchery to sex them and be 100% positive that they were all hens, I would have gladly paid more money for them. Now after 16 weeks I will be having to say goodbye. From reading other posts, I know this happens ALL the time. There just has to be a better way to sex the chicks.
