My hens comb was all white and flopped over today???

[Willow's Meadow]

When I went into the coop today I noticed that one of my 6 month old Buff Orpington hen's comb was all white and flopped over. I notcied the comb is much bigger then the other hen's combs and is taller. But it was all flopped over and white....it looked really weird. They did just start laying so maybe that has something to do with it. I know she's not a rooster because we only have 2 and they look completly different lol!!!! So is it normal for her comb to be flopped over??? She is the only chicken that is like that. Why is her comb flopped over and slightly white/pinkish instead of red like the other chickens???
