Whether you cover or not depends on what type of culture you are trying to grow, so you need to do a little research first. There are two different fermentation processes anaerobic (or airless) which requires an air tight lid or airlock. If you use an air tight lid instead of an airlock, it is important to burp your lid to allow gas to escape preventing an explosion. The second type is an aerobic fermentation, also called "wild fermentation". This process uses an open jar with a cloth cover that allows air in & pulls cultures from the air. Either way you need to make sure that whatever you are fermenting will survive in the environment you are creating. Usually if you are fermenting in an anaeronic environment you would make a salt brine to kill unwanted bacteria first & allow the lacto bacteria to survive. If you are fermenting in an aerobic environment you need to make sure what you are fermenting has enough natural sugar in it to support the lacto bacteria. If these conditions are not met you are just growing unwanted & harmful bacteria (such as bottulism). Fermenting feed is a great way to keep your flock healthy, but if you don't know what you are doing it can quickly become disasterous. FYI, a ferment that is done properly will always have a slightly tangy smell.
