Only need 12 to 24 hrs with back slop, or it could get gross and the birds think so tooNo, we do not backslop. We tried the never ended bucket method at at first (take some add some to replace) and it got GROSS!After that I chose to go to the polar opposite and start with a clean container each time. I was thinking about growing a mother culture like sourdough and adding a small amount to each batch, but that may get gross too. We get fairly good results with a 3 day ferment. Not sure if the 1/2 gallon containers will be different than the quart jars in results after 3 days. We will have to see. I could always go 4 days if needed by just adding another container to the cycle.
I do add pepper to it sometimes. I like to just mix the pepper right into the scratch mix. We also will sometimes just chop peppers and give them to the birds. I may start playing with turmeric too. I hear/read that it has a lot of health benefits for the birds (and us).
