Do baby shrimp usually hatch pretty much at the same time or over a period of time? In one tank I just have 5 CRS and 3 are berried. I see at least one new little baby but a day later the shrimp that I suspect is the mom is still berried (all 3 are still berried). So I either had the other female berried that I was not noticing maybe because she just had one or two eggs left, or they seem to come out over time. Mainly just curious as I was not expecting to see the baby and trying to figure out where he came from.
