Droopy comb

[DAO6603]

What would be the cause for a hens comb to droop and lighten in color?

It could be many things. I have a couple hens whose combs are severly drooping but the hens are healthy and laying. What breed are they?

She's a Rudd Ranger, 18 weeks old. Has layed about a dozen eggs, but hasn't layed in 3 days. Eating, drinking and moving around just fine. Temps have been in the high 90's with high humidity.
