How long until frozen bloodworms?

[ShaiOphelia]

Hello hello!
I got eggs (hatched on the first, so 18 days ago). The lady I got them from was lovely- but pretty much told me to google. So I got home and they were already hatching- and I had to stagger to figure out what to do with myself. Fast forward- I now have 16 healthy babies to take care of, and a DIY youtube brine shrimp hatchery that I made, which broke down and almost killed the lot when my cat broke my only suitable lamps and spilled my eggs- causing two of the babies to seemingly have permanently crooked tails- and are half the size of the others. Not sure if any of you have seen that phenomenon before...
But all have survived and I move forward with full determination and willpower.

I have been scavenging the internet by myself trying my best to make this work- and while there is so much useful information, I am pretty uncertain on a lot of things still. My babies have little front legs (not fully grown) and no back legs as of yet. They are still on brine shrimp- but I want to know when I can start them on frozen food, so I can re-home some of them. Some places are telling me 2.5 weeks- but I don't want to choke them. Other places are telling me I need to wait for legs- does that mean front legs? hind legs?

I'm sorry if these things have been aksed before... Any help would be greatly appriciated!

I started mine on a mix of bloodworms and brine shrimp when they had their front legs. I cut the bloodworm cubes up so the worms wouldn't be too big. I did a mix of that and shrimp; it got them to understand it is food. Then I went to just bloodworms. When I did, I kept a close eye on them because a couple weren't catching on and I had to mix brine shrimp with them a little longer.

I have a baby that is a little over two inches that has a twisted tail. I thought it would die as a baby but it is thriving. I attached a picture of it.

Thank you so much for your response! Ive started to cut bloodworms really small and include them with the brine shrimp, many of them try to eat them but spit them right out again. I'm not sure what that means- but I assume it means defeat lol.

It's pretty stressful- the two that have a serious kink in their tail aren't actually growing very well, and are about half an inch smaller than their siblings. One of them seems to prefer to dwell at the top of the water while all the rest like to dwell at the bottom- which is strange...Its like he floats- but he still has good reaction and swims away if I boop him with my finger. So I know he isnt dying- but i'm concerned for him.

We seem to be having another batch of 60 babies coming...Bah!
