Boy, I couldn't pinpoint a weight or age when I went to every 7 days. If they are up and roaming, what the heck, feed em. I think once they get a wee bigger, and you don't see the roaming, then you can decide to push to 7 days. I tell you what though, my bee knows when day 7 is and you don't dare miss it. I had eveybody off on goofy feed days due to shed and what not, thought I would make her wait and extra day so I could make one trip to get rats (Don't have any big enough rats or Asf's here atm). Boy was she not happy with me. She's an absolute pig. I think you can tell when they are ready. Sorry I don't have a better "concrete" answer for ya.
