TX, I have no idea about your chick. It's so hard to diagnose chickens, let alone chicks and I do not profess to know much and certainly not enough over the internet to say. I think the ecoglow was not enough heat for them in our drafty old farmhouse and allowed whatever illness to overtake the stressed chicks. The question is, what illness did they have, was it carried in the egg and should I introduce them to the flock when they're older? I hatched a second batch and they are having some illness as well at the same age (1 1/2 weeks old) but I did not use the ecoglow so it's not only the cold but a variety of factors. A heritage buff orpington chick died this afternoon after being lethargic only this morning. Very little warning and nothing I can do for it. A few of the rest show the same respiratory symptoms as the first hatch did, stuffy sneezes. But thankfully, it's not most of the flock this time, just a handful of chicks. They are in an adjacent brooder in the same room so it's entirely possible that the first brood infected this one. They were from different eggs. I don't know. I get overwhelmed by all the factors involved. Thought about sending the dead chick for a necropsy but don't want to spend $100. Then again, if it means saving the existing flock from an infectious disease, it would be worth it.
They're dropping like flies.
