I feed mine once a day, in the evening. I just feed it to them the very next day once I made it. It can't be fed in metal and it has to be fed in plastic because it will corrode the metal and it wont be a good thing since it will get bad stuff into their food from it leaching out into it. Some use the acv in theirs but I use it in mines water. I was once a rookie to. We all have to start some where. Are the hanging feeders plastic? Once I got my fermented food made, I started feeding out of it the very next evening and I didn't offer them a choice in the foods. Some leave out the dry stuff and some don't and I didn't either. Thing is, this is some very good stuff for them and mine dearly love it. For some reason and I can't remember why, but I did have some dry in a hanging dish I used to have and they wouldn't eat it once they tasted the ff. It was in their roosting area and it took them days to every finish it off once they got the taste of the ff. Even if they wouldn't eat the ff, I would have kept it in there and not give them anything else so they would eat it because it's just so much better for them than the dry food was.
