Is this normal poop?

Very lethargic/sick chick. Was fine yesterday. Only 3 days old. Can’t stay awake at all and not eating/drinking. Been syringing electrolyte water and egg yolk but hard to tell if there are any changes.

In a brooder with 9 other chicks. Hot side is 100 and cold side is 80. They have access to clean water and chick starter.
