Chicken Behaves Like She Can't Breathe Good

[CallieinChrist]

I noticed today one of my Easter Egg hens was hanging around the laying boxes all day. This evening when I went to give them their evening scratch and collect eggs I noticed she was stretching her neck as if she was struggling to breath. She made it up to the roost with the other hands but she's still stretching her neck like she's trying to breathe. I haven't noticed anything unusual with her poop dropping yet and I'm wondering if anybody can give me some suggestions on how I can make her more comfortable and hopefully getting her in a place of breathing better again.
