Increasingly concerned about size variations in 10 day old fry (Pics included)

[Trippy]

So today I have noticed that the fry are not uniform size. I have an estimated 100-115 but while trying to count I noticed that some are quite large in comparison to others. I'm feeding newly hatched baby brine 6-8 times a day and water changing 50% twice a day or 80% once a day. I tried to grab a couple of pictures but I'm not surer if they convey what I'm seeing. Is there anything I should do or is this just a part of the process?

Don't be concerned yet. Wait for them to get a little older. I don't start looking hard for culls until the kids are a month or so old.
