My favorite hen has been looking a little sluggish for the past few days. I didn't think much of it, really, until I picked her up to kiss her and smelled the stench of rotting death coming from her beak. It's not a sour smell; it's a smell like rotting meat. Actually it smells exactly like when the hens break eggs in their nest and then the eggs ooze into the straw and get all rotted and maggots form. Super gross, I know. Has anyone ever smelled this coming from a chicken's beak? It's definitely coming from her beak, not any other spot on her body. She is walking around the house now, ate a little corn and water. She's not acting super sick, just kind of blah. Thanks for any input.
