Releasing is a quick way to spread diseases, when you release you are disrupting the carrying capacity, (The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available in the environment. In population biology, carrying capacity is defined as the environment's maximal load) so when you take an animal from its environment (your chicken coop) and release it to another, you are dooming the raccoon anyway, Its a stranger to the area and will get in territorial fights, get wounded and possibly spread diseases. Bear foot is right, if you're not going to kill it, don't trap it..... Sad but true.
