I'm new to raising chickens and am learning all the time thanks to this great forum. I have 16 6 month old chickens that have been laying regularly. Today I had a hen run out from under my deck and flap its wings very wildly. Two of the other hens were following closely behind. It's neck was stretched forward but its head was down. It went headfirst into the ground and stayed there for a few seconds. I had never seen this behavior before so I wasn't sure what was going on. The other two chickens pecked at it a little bit and then it's legs twitched. It took me a couple of minutes to get to it and when I went to check on it it was dead. I believe the chickens pecked it's comb because there was a tiny bit of blood but it only came from that small spot. Her comb and wattles were really purple, not red like they normally are. Her eyes were closed. I called my dad who helps me from time to time and we thought it might have broken it's neck. He suggested I clean it to see if there were any markings in case a snake bit it and if I found nothing I could go ahead and eat it. I found no puncture wounds on it at all. I'm just looking for feedback about this and to find out if it's common for chickens to break their necks like that. I would like to be able to eat it if possible because the chickens are being raised for meat and eggs. None of the chickens have shown any signs of odd behavior or disease before and they are all foraging, pooping, and eating feed like should, nothing out of the ordinary. Can anyone help?
