REALITY ... chickens  have blood  according to  oureverydaylife.com .. it is  possible for  PROPERLY "COOKED "  chicken to appear red , or even "BLEED"  at the  thigh bone , Even after cooking , it  might contain some dark  red blood ..

. it might be unsightly or alarming to some  people  but is NOT a food SAFETY RISK

BONE MARROW ( the source of the  coloration and blood  )  is SAFE and even nutritious to eat  according to  food safety   investigators regulators  and nutritionist  

Thank you for the question

Just leave the chicken cooking in the soup a little longer then it will be fully cooked.

As long as you continued to cook the soup until the meat was done.

Regardless of how you cook chicken it has to be completely cooked, no blood at all.  Chicken undercooked is one of the worst things to eat as it can give you food poisoning.

It is not blood. Rather it is collagen. All commercially processed chicken is blood free, by Federal Law. 

Just continue to cook the chicken till juices run clear or in the case of a soup, a meat thermometer place into the meat near the bone reads 165 degrees or higher. For a soup, the chicken should be falling off the bone anyway. 

As long as you continued to cook it until the meat was cooked thoroughly, there is not a problem that "bloody" juices came out of the legs during cooking.  (It isn't actually "blood".)  

The juices would have cooked in the soup.  

No chicken that you buy in a shop is going to contain blood. After slaughter the carcass is hung upside down and the blood drains from it.

Of course, in certain places, parts of the meat remain pink or even red. It's never going to happen though that “blood comes out”.

If the chicken was cooked properly the it is “edible to eat”.

So long as you continue to cook it through, that's perfectly fine and normal. Blood is just protein. Humans can and do eat it both raw and cooked all over the world.

not if you are a Witness
