Is this Cocci? Intestinal Shedding? Worms!? Silkie 4 months 3 weeks old!

How old is she?
I agree with @Eggcessive I would treat for worms using Safeguard or Valbazen these will treat most worms, but not tapeworms. I don't see tapeworm segments - maybe you can point those out?
Does she have grit?

This is what tapeworm proglottids look like

Melody, outstanding video! Wow, that poor chicken was quite overloaded!
