I am brand new to chicken keeping. I have these three birds that were born on January 29th (I incubated and hatched 7, kept these three hoping that they were all hens). Now they are 8 weeks old. I think that they are Dominiques. I am wanting to keep three hens strictly for laying and am not able to keep any roosters where I live. Within the last couple of weeks, two of the three have periodically been screeching (not a full-blown crow)and those two are developing combs and wattles and one isn't. Can anyone give me a solid answer on their gender? Any help you can provide would be greatly appreciated!!! If two are roosters, then I need to get rid of them before my neighbors kill me! ) If you have questions about them to help you determine their gender, just let me know. Thanks, in advance, for any help anyone can provide!
