Hello beautiful fellow chicken lovers, I need help sexing 4 different chicks. Each a different breed. They are all around 5 weeks old. #1, I think is a Porcelain D'uccle, #2 is a Millie Fleur D'uccle, #3 I think is a Golden Seabright and #4 I think is a OEB but color might be a BBR. What sex do you wonderful people think these sweet bebes are? I appreciate any and help! Thank.you!
