Thanks Peewee and JJ,
Its hard for me to report that the little guy passed away last night. At least he was with his friends. When I took the body out, they cried for hours for him. I cleaned the brooder out again with bleach and all food and water containers were cleaned as well. The two other ones are thriving. I gave them their first meal worms this morning and they went nuts. It seemed to cheer them up.
Thanks for your support.
Coryza is very bad and people need to understand that what might end up as a simple bacterial infection could be much worse. I incourage people that keep birds - if you see one not looking itself isolate right away. Then clean everything with bleach water. Prevention is way better than the cure and in alot of cases there isn't one.
Take care
Martha
P.S. He was the surviving chick from the double yolker that hatched. He was the stronger of the two chicks, but my vet said that probably was the reason for the early hatching and the yolk problem.
But it was so interesting to see. My daughter took the egg shell to school with her to show her class - how one came out one end and the other came out the other. I had a photo of just after they hatched, will see if I can get it back from the school and scan and post it, as my husband deleted it off the memory card - grrrrr.
