That is a retained placenta which is very dangerous to the mare. Red bag delivery is when the placenta detaches from the uterine wall prematurely during delivery and is presented first before the foal. This is very dangerous for the foal since the placenta blocks the passageway and stops giving oxygen to the foal when it detached from the uterus. The term "Red Bag" directly refers to the red placenta being presented first during delivery, you only have minutes to get in and get the foal out to reduce the chances of a dead or dummy foal. Dummy foals are named that because they went too long without oxygen and their brain was damaged, causing all sorts of potential problems.
