I have a few questions about sexing RIR. 1. Feather sexing: Can you feather sex RIR? I tried with my chicks but they all look like hens and I don't think that cat be right. Could you help me? 2. Vent sexing: I tried but I'm not sure what I'm looking for exactly. Could you help? 3. Marking sexing: I've done some research and some people have said you can sex RIR by their markings. I have some chicks with black dots on their heads and some with black lines next to their eyes. One of the chicks has stripes and is a lot darker. Could you help me? Please help me sex my chicks. Thanks.
