I wouldn't risk it and have to possibly dump out all that feed into another place while replaced plastic liners. Too fussy and fraught with difficulty.
yeah ive still got about 100lbs of feed left so i should get something next week anyway or ill never have a proper ferment i should have like 2 bins going... but im amazed as to how much feed i have left... id be almost out and its only a few days in... i was feeding out 75lb a week maybe a bit more
