Normal. Chicks don't need to eat or drink their first 3 days of life, any water they send would just spill and chill the chicks so they just ship them as fast as possible so they get to you in that time frame.
If you feel like you need to rehome them, that's totally fine, if you want though you can post a picture of your setup and tell us what their diet is and we can try and offer suggestions. Of course, no need to if you don't want to and it honestly does sound like bad luck and perhaps some bad genetics
I wish you and them luck in any case
