Is this silkie poo normal

[Bryce Thomas]

The poop is sometimes like this from all of my chickens. Sometimes it is like normal chicken poo, black and white and faintly mushy. Other times it is like this. I give them:
Constant access to feed and fresh water, love, shade all over and on top, a mister for the heat, they live here in Arizona so they are very non heat tolerant so shade and water is EVERYTHING. I make sure to have literally everything for them.

They are always: alert, active, have clear eyes, no external or internal parasites and never have once showed any illness or anything

So are these yellow poopies normal?

My birds have them, so that type is probably okay

Could be a cecal poo
