Got a new round of chicks and I have been fermenting the organic crumbles i have them on. They love the mash and seem to be doing well at 1.5 weeks old. Since they grow so fast, it's difficult to tell how much they will eat, so to keep the fermentation chain going faster as their needs change, i have been transferring the liquid from the prior batch to the new batch to kick start the process. My question is, how many times can I do that? Is there a point at which that might become unsafe? So far, each batch has smelled appropriately fermented with no bad odors or mold, but as chicks, there isn't much room for error if I make them sick, so i wanted to know of there is a problem with continuously starting a new batch with a continuous chain of liquid from previous batches.
