Comb turning black and droopy

[jobydog]

One of my Rhode Island Whites has developed a blackish discoloration on her comb and it is droopy. This only happened within the past couple of days. She is eating but has had a "dirty" bottom for awhile. As far as I known she is laying. She is about 2 and 1/2 years old. Any ideas?

Can you post some photos of the comb, the bottom and the whole bird?

Bring her in and clean up the bottom so you can see what's going on.
Feel her abdomen, does it feel hard, soft, fluid filled, etc.
