Poop question with picture

[CarneyChicks]

Does this look like a worm or anything to you guys? I found it in the yard so not sure who it belongs to either.

How old are they?
Could be a worm, something long and stringy they ate or intestinal shed (but that is usually red colored).

General worming info is: Valbazen 1/2 ml orally and then repeated in 10 days for each chicken or Fenbendazole (Safeguard, Panacur) at 1/4 ml per pound for 5 days in a row.
