Wheezing chicken

[shmccarthy]

I went to feed my chickens and noticed one of the hens is wheezing loudly with every breath. She is walking around noamal and eating normal. She is a year old and on another note I found a double yolk egg today too. I don't know if she laid it but there were as many eggs as chickens so I know she laid one today. What could this possibly be??

None of the other chickens are doing it and she is acting completely normal except the wheezing. I'm really afraid to lose her as she's such a sweetie and my best layer. I don't want to take her to the vet if its something I can easily fix but I don't know if it is something that is easily fixed.
