My 9 3-week old chicks went through 7 cups of chick crumbles between 10am and 7 pm yesterday. I refilled with 8 cups of feed at 7pm and so help me it's almost gone again...?! (current feeder only holds about 8 cups). WHAT is going on? Is this normal? I knew I'd have to buy a new feeder for them as they grew, but I seriously didn't think I'd need it this quickly. Heck, this IS a new feeder (1 week old!). Once they're big enough to stand cold weather, I can convert my coop from a brooder into a real coop (by opening the ladder to the "downstairs") and they'll have access to the coop's feeder which holds a 50-lb bag of food... but that's not for a while yet. What to do? Also, I bought chick grit from MM but it looks BIG...?! And they just send it in a clear ziploc bag--no labelling. So I'm not sure if it was mistakenly packed as "big bird" grit or what. It looks like tiny stones. The stones ARE about 1/2 to 3/4 the size of their chick crumbles... I'm not sure I was mixing it in the right ratio for them. The crumbles were advertised as needing additional grit (Rogue organic chick crumbles). I went with some sand for the first week because they were so tiny. Any insight on this?
