Worm Identification please--poop pictures

[dawg53]

Thank you so much @dawg53. I very much appreciate your taking the time to help me. And I must admit, I'm pretty happy to hear no worms!

If you have another minute, would you mind checking these two pictures? These were from the sick hen previous day and what got us started thinking we saw a roundworm--near the edge at about 5pm. Does that one look like a roundworm to you? If so, would you treat everyone or just this one hen?

Yes, that is definitely a large roundworm.
It would be best to worm all your birds with Valbazen. Chickens constantly peck the ground/soil and in doing so, they pick up worm eggs and swallow them starting the worms lifecycle. Redose your chickens again in 10-14 days.
