It is definitely the cold. This time of year even with a full batch of 25 "for warmth" it is way too cold. You order in winter and you take your chances. I can't believe the hatcheries even ship this time of year. Twenty two degrees? Thats 10* below freezing! Hello people, why would they think chicks could survive that?
Um a lot were DOA. The second batch she got she opened it up and she said their were bodies everywhere. The rest died with in a few days. The first batch she got was a week ago. She got the second batch today. The other ones were the same many DOA or very week and die shortly after. Very sad here is the thread if anyone wants to read it. https://www.backyardchickens.com/t/626647/theyre-heeeeeeereeeee#post_8364072
