I had a club member give me a YB and it has gotten sick. I have 60 YBs and none has shown any sign of sickness. I have had it contained for week and it still does not seem any better. The front of the throat is swollen up and you can feel the tube that runs in the throat. it has gotten very thin and does not look good. I looked in the throat and it seems to look pinkish. Any suggestions?
