One of my 21 week old Tetra Tints was found dead in the coop this morning! She seemed perfectly fine last night and had absolutely no issues thus far, even laying pretty regularly! When we found her she was already gone and the other hens were pecking at her. I did find that she layed an egg earlier this morning and it had blood stains on it! I am a newbie to raising chickens and this just totally devastated me!
