Is this normal chicken poop?

[Wyorp Rock]

Thank you. I ordered some yesterday, received it today but worried about treating her for something she may not have Will it he okay for my other birds to be treated as well? I only have 5 hens and a rooster. Three buffs and 3 RIR or Cinnamon Queens .. Idk? Anyhow, Ive raised them all since they were we chicks from TSC

The Corid won't hurt them.
