I am just going to finish this thread.
The little chickie finally laid down on the heat pad and slept there. It woke once and stood up all afternoon but didnāt eat.
In the evening it was down and it passed away shortly after. I could tell from the spasm in the legs that he was on his way out.
He died on the 5th day.
That evening I delivered the single chicken that was left, to another flock that hatched at the same time. This one was kept with a premature looking tiny chicken and he is going to become part of their flock, not for sale.
Thanks to all the responses.
I never want to hatch again unless I use proper eggs, and only when I can work from home. It really is like having a baby. You wait, watch, listen, you worry and donāt sleep and you are ready to help and take care of them. It is overwhelming.
