I am hatching! One of the first has a red umbilical cord that has a chunk the size of a dried pea at the end. Is this his reproductive parts? He is bright and active climbing all over the eggs dragging it along. Bright eyed. He is a goer. Do I need to cull or keep and see if it reproduces? I am not as sentimental as most on this forum. I was raised on a ranch. I really don't want to raise a chicken that cannot reproduce. I like eggs and baby chicks, chickens who do their thing. However I don't want to cull needlessly.
