You can use a bowl with a plate on top of it. I use a 5 gal bucket with apizza pan on top. The bucket i feef from haa no lid. I have a 2 bucket rotation. One that i feed from and one that is fermenting.
So the fermented feed had been working well for well over a month using the backfill method however for the last 2 weeks they have not been wanting to eat it...no mold, no strange smells same dry crumbe...yesterday I offered dry crumble as well as the mash...still not eating much any questions? I have dumbed the last of the mash in the compost and have started over any other suggestions? is it feed fatugue ?
