Less than I estimated but still okay for price
Obviously you have no control over what 4lbs is, the amount was less than I imagined. Ordering online is tricky as far as picturing what you are actually recieving. The size of pieces is perfect for our adult chickens. They seem happy with it, I've had to refill their dish just a few days after initially filling it. I'll be looking into a bigger bag for any future purchases because the 4 lb bag won't be lasting long. We have 5 chickens, I think their calcium need is higher at 6 years old. So this bag might last longer for someone with younger chickens. Otherwise I recommend comparing the 50lb bag with other options.

Glad to find a large bag of oyster shell alt
Ordered this oyster shell alt because our girls were laying some soft shells. We'd tried another brand before, but the bag was so small that we went through it in just a couple weeks. I was happy to find the 50lb bag available through MileFour--hopefully it lasts quite awhile. It's too soon to know if it's making a difference in the shells, but the ladies seem to like it!
