Folks please, please , please.
You have got realize that stress can kill just as fast a anything. These chicks most likely were just worn out. Of course they won't open their eyes. Would you if you were double dog tired? The reason folks put lights in the hen house is so the chickens stay up and eat, eat, eat.
These two should have been put in a dark warm place and allowed a few hours of sleep.
They most likely were tired and then folks go pushing food at them and vitamins at them and bam! They drop over dead.
The basic chick starter has everything they need. PERIOD! And clear , clean WATER. That's it. They do not come from the hatchery sick they come STRESSED!
In two years I lost only one chick and that was a day after it hatched.
I had two from the hatchery that were just like these two. I put them in a box by themselves with food and water and closed it over and let them rest for a couple of days checking on them every now and then. They came through just fine.
To much vitamins can cause KIDNEY failure.
Did you know stress can cause pasty butt. I have not had a case of pasty butt in any of my own incubation raised chicks. The only time I had it was when I bought my first 25 from a hatchery. Folks I think are killing chicks with kindness, fussin and treating them to death.
Please just the basic chick starter and water. That's all they need. For heavens sake they are babies. Let them sleep. Stop pokin and prodin and ohh here have some treats.
