I have a peachick that is 14 weeks old. She is in the pen with mother and father. I feed her 1 chicken egg a day and they have free access to gamebird feed. I also give them scrap vegies from garden and bread. She acts healthy, running around pen, but has started to sneeze some and cough within the last few days. I treated parents last winter with safeguard for chokeworm. I don't know if you have an idea as to what is wrong with her.
