Droopy comb

[margcook]

One of my hens has stopped laying eggs the last 3 days, I've noticed her comb is droopy and she's been standing with her tucked in close. She's been eating normal, just not her usual food aggressive self.
Wondering if this sounds familiar to anyone or if anyone has any possible ideas what it could be?
