Swollen eyes and gasping for air

[jsuhre]

I started noticing my chickens getting swollen eyes and some are gasping for air. It started out with 2 chickens getting swollen eyes and now about 20 of my hens, roosters, and chicks have it. Any idea what the problem is or what I can do?

Sounds like a respitory infection to me, I would give them some electrolytes and definitely separate the ones showing symptoms. Hope they get better.
