First, the CO2 is supposed to leak out of the fermenter. Otherwise it will explode. If the bucket is leaking, air is NOT getting in, CO2 is just escaping. That's fine.
After 60 hours, I'd say it's almost time to repitch some fresh yeast in there. Oh, what temp is the fermenter at? The colder it is, the slower the yeast will be to take off as well.
Also, leave it alone! moving the wort from one fermenter to another is only going to increase your chance of contamination.
