I have three day old chicks I had mailed to me from a hatchery as I'm only aloud 3 chickens where I live, 2 salmon faverolles and one lavender Orpington. The Orpington and one faverolle are acting fine, eating, running about, napping. Doing chick things. The 3rd stands alone most of the time and peeps loudly, ear piercing like. Sometimes scurrys about like normal then goes back out on its own and starts peeping. The other two act completely normal, so it can't be the heat or they all would be upset right? When we first received them yesterday the one wouldn't drink or eat so I was sure we were going to lose it. Now it eats and drinks, not like the others but she is doing it. So what's the issue? I'm lost!
