chicken having trouble breathing

[catsapp]

One of my chickens (around 3 month old EE) has been having trouble breathing. She's making high pitched, weezing sounds with every inhale, and about every 15-20 breaths, she... kinda looks like she's having a sneezing attack complete with loud, hacking squawks.

Any ideas what could be going on with her?

What should I do?

a great med for respiratory illness is tylan50 injectable. dose for large bird is 1/2 CC small bird 1/4 cc. once daily for 5 days.you can find it at feed store. don't worry it says for cattle and swine many many poultry owners use it including myself and it packs a punch against respiratory illnesses.
