i am currently raising 13 1 week old baby chicks of various breeds. I incubated and hatched then from a friends farm. I have 2 chicks that are shaking their heads a LOT, almost like a sneeze, and one was panting but now is just breathing hard. I have separated them and have given some food and water. They have great appetites and are drinking ok too. Seem fine other than 2 symptoms above... any ideas?
