You need to relax and take it easy. No need to stress it. Quails can look after themselves from day 1. Just provide feed, water and most importantly, heat. A weak or struggling chick is really not worth saving anyway. I just hatched a dozen japanese quails myself on day 16. Waiting for the next 4 dozen to hatch. I will suggest you get some fertile japanese quail eggs as well. Better egg laying and better feed conversion. If you have any questions or problems, i know this really awesome place where you will definitely get all the answers and expert support from seasoned poultry veterans. It's called backyardchickens! You might have heard of it? ; ^ )
