Also the one that didn’t look good is looking worst today. Like turning the whole egg purple.

The temp is 89 and he is doing great in the brooder now. Just won’t let me leave his side.

Can you post a candling pic of it? It may have quit. If it did it's not your fault, there was nothing you could do. Sometimes they're just too weak to make it.
It should be at least 90. 95 is better.
