The comb discoloration could be a circulation issue or lack of oxygen. Unfortunately, it sounds like this hen is on her way out.
Green watery poo is a good indicator thay she's not getting enough food. It can also mean worms or other internal infections, but this isn't always the case. What color are her urates (the white portion of the poo)? These will discolor to yellow when there is a strain on the kidney or liver, which can be caused by medications and some foods, but in their absence may be an early sign of organ failure.
You should check over her abdomen and compare it with one of your healthy birds. - not any hot spots, lumps, swelling, or just anything out of place, really.
Also, how is her breathing? Any signs of mucus from her nostrils? Or has she had a respiratory infection recently? I've heard these can jump to the reproductive system.
Please note that this bird's poor health would not be related to a mild case of bumblefoot - there's definitely something else going on. Likely a reproductive issue as has already been mentioned. Unfortunately, these tend to be hereditary, so would not be a very good prognosis.
