My local feed store told me to feed them the 'start and grow' until 20 weeks. I'm nearing 20 weeks now and am getting low on feed and need to replenish but not sure what to get now. I haven't yet provided grit, but there is sand in the dirt of the run and I've seen my roo eating small stones from the sand even though I've not been feeding the scratch yet. (not sure why I haven't given them scratch yet... kinda got the impression it was junk food? Plus worried it's too big! But should I start that normal for them to want to eat small stones when there feed is crumbles? The occasional treats I give them are fresh (untreated) grass clipping. grapes, tomatoes, plum, cottage cheese.... I'm also considering 'organic' feed, but haven't seen any available (yet). I don't mind paying extra since I only have a few birds, but I do need convenience! How can I set up and feed them where they will all get what they need nutritionally? I recall that the hens need extra calcium and just wonder how to make it work since they all live together?
