Sorry I don't post often, but I need help! Woke up to two of my 4 week old pullets dead in the brooder. I don't know what happened at all. Water and food. No trauma visible. We moved the two that were still alive out to a dog kennel in our lawn, and offered new water and food. They are eating and drinking but seem to extend their neck a lot when doing so. The americauna chick seems to be foaming a bit at the mouth. We emptied the brooder. What do we do about the other chicks? What could have happened?
