One of my oldest hens has very labored breathing today, she seems to be really having a hard time.   Poop is normal, she has showed signs of wanting to eat and drink and other than here breathing hard she seems normal.  I don't want to just give her antibiotics if they are not needed but I feel like I need to do something.  She was wormed with Valbazen over a month ago and has not had any change in feed.  Her eyes are bright and she is not molting.  Any thoughts?
