Why does my chickens poop look like this?

[Jordy2123]

i have been struggling with upper respiratory infections and coccidia with my chickens. I had a rooster and a hen die. I just finished a five day treatment of corid for my whole flock. Let them out this morning and someone’s poop looks like this. I need help.

It looks like they have worms.

Can you take some samples to your vet?

I'm sorry that you had 2 die, it would be a good idea to have a necropsy if you lose another. If in the US you can send the body to your state lab https://www.metzerfarms.com/PoultryLabs.cfm

If you can post some photos of the chickens and housing that may be helpful.
How old are they?
What is the upper respiratory infection (symptoms) and how have you been treating it?
What do you feed? Have you been giving any vitamins/supplements? Treats?
What dose of Corid did you use?
Where are you located in the world?
