I have a 6 month old hen. Very healthy this morning. 15 minutes ago I checked on her (checked on the flock) and her cheeks are swollen. Both sides of her face right where the 2 halves of the beak come together. It looks like she is puffing out her cheeks like a child would. Right now I don't see any discharge of any kind. She is running around fine, not sure if she is eating or drinking and her eyes are open and not puffy.
