Depending on how much FF you use a day why not make an extra bucket of it, if you need to, so that they have the FF while you are gone?I'm curious what you do with your fermented feed when you go away for a few days? I'm not sure that I could get our normal chicken sitter to worry about replenishing the feed over a period of days. But at the same time, is it ok to just have a batch sit for 4-5 days without being eaten?
I know mywhen I asked chicken sitter she had no problem feeding the FF & I always make sure there is enough to last while I am gone. If one bucket empties there should be enough to feed the Mother till you can replenish it.
