Easiest way is just to grab a hold and pop the head clean off. I've heard people snipping off with extra sharp scissors, or taking a kitchen knife, but I much prefer my own hands. I can then thank the chick for the time he gave us. I know it sounds cheesy but I feel connected for a last minute and truthfully sorry I had to be the ending factor.I'm just curious. There was a couple of times that I really did feel that it was the best thing to cull and once I finally convinced myself that I was gonna do it I just stood there with the chick in my hand and then realized I had no idea how to do it. I know how to cull grown grown chickens do you do chicks the same way?
