Need HELP.. Chicks dying after incubation

I just had a decent hatch of 10 mixed breeds of chicks. They came out of shell very good but after 2 days in the brooder box i had 3 die so far. I don't know whats going on here. Possibly not eating???? I had put all there beaks to the water and food and they seemed to get it but some chicks that have there eyes closed all the time don't look like there going to make it. My brooder is at 95 deg. I am feeding them chick starter that i tried to mash a little also. I don't understand why some wont open there eyes. Any help would be greatly appriciated. thank you
