so... i soaked chickpeas for 18 hours... now they have been laying on damp cloths and covered with damp cloths for about 18 hours and i've been noticing a faint smell. not good, or bad, but there. kind of sour. i've been washing them about 3 times a day... rinsing and squeezing out the rags. some of the chick peas have also cracked in half and some look like they're shedding. did something go wrong? should i continue letting them sit?
